The questions are asking about unit prices (price per 1 unit of thing)

we want to find out which is the better deal

we want to find out which price/1item is least (you want to pay as little as possible per item)

so to solve each problem, divide price by number of things to get the unit price (price per unit)

1) $25.00 for concert tickets for 2 people or $36.00 for concert tickets for 3 people.

$25 for 2 people is $25/2=$12.50/person

$36 for 3 people is $36/3=$12.00/person

12<12.5 so better value is the $36 for 3 people

2) $380 for a bus for 32 people or $420 for a bus for 38 people.

$380 for 32 people is $380/32=$11.875/person

$420 for 38 people is $420/38=$11.05/person

11.05<11.875

$420 for 38 people is better value

3) $4.25 for 4 liters of milk or $2.55 for 2 liters of milk.

$4.25 for 4 lieter is $4.25/4=$1.06/liter

$2.55 for 2 lieter is $2.55/2=$1.27/liter

1.06<1.27 so $4.25 for 4 liter is better value

4) 35 grams of mixed nuts for $0.99 or 59 grams of mixed nuts for $1.49

$0.99 for 35 grams is $0.99/35=$0.02828/gram

$1.49 for 59 grams is $1.49/59=$0.02525/gram

0.02525<0.02828 so $1.49 for 59 grams is better value

5) inline skate rentals for fat $30.00 for 4 hours or $54.00 for 7 hours.

$30 for 4hrs is $30/4=$7.50/hr

$54 for 7hrs is $54/7=$7.71/hr

7.50<7.71 so $30 for 4hr is better value

6) 500 sheets of paper for $9.45 or 4500 sheets of paper for $49.00

$9.45 for 500 sheets is $9.45/500=$0.0189/sheet

$49.00 for 4500 sheets is $49.00/4500=$0.0108/sheet

0.0108<0.0189 so $49.00 for 4500 is better value

7) 25 liters of gas for $21.50 or 35 liters of gas for $40.00

$21.50 for 25 liters is $21.50/25=$0.86/liter

$40 for 35 liters is $40/35=$1.41/liter

0.86<1.41 so $21.50 for 25 liters is better value

Answer: The answer is A 17in2

Step-by-step explanation:

In the question it states that the triangles are congruent (both the same).

first I found the area of the top orange triangle.

the formula to find the area of a triangle is $\frac{1}{2} bh$ (base times Height).

so I did $\frac{1}{2} 3.23* 5.12$ which gave me 8.27.

Since the triangles are congruent (the same) they would both have the same area along with base and height. so I multiplied 8.27 by 2 (because there are two triangles) and got 16.54 which rounds up to 17.

the question also stated to find the APPROXIMATE area (close to the actual, but not completely accurate or exact.)

A freight carrier charges $0.57 for a package weighing up to one ounce plus and additional $0.32 for each additional ounce or fr

kherson [118]

We have to write an equation that uses this info so we can find the cost to ship that package. However, the package weight is given to us in grams and we need it in ounces. So first thing we are going to do is convert that 224 g to ounces. Use the fact that 1 g = .035274 ounces to convert. $224g*\frac{.035274oz}{1g}$ . Do the multiplication and cancel out the label of grams and we have 7.901376 ounces. Ok. We know that it costs .57 to mail the package for the first ounce. We have almost 8 ounces. So no matter what, we are paying .57. For each additional ounce we are paying .32. The number of .32's we have to spend depends upon how much the package goes over the first ounce. For the first ounce we pay .57, then for the remaining 6.901376 ounces we pay .32 per ounce. Our equation looks like this: C(x) = .32(6.901376) + .57 and we need to solve for the cost, C(x). Doing the multiplication we find that it would cost $2.78 to ship that package.
