1. To solve this problem, you must make a System of equations.

 2. The equations are:


 d+g=22 (i) 
 0.75d+1.25g=21 (ii)

 3. If you clear "d" from the equation (i), you have:

 d+g=22
 d=22-g

 4. Now, you must substitute d=22-g into the equation (ii):

 0.75d+1.25g=21
 0.75(22-g)+1.25g=21

 5. When you clear "g", you obtain its value:

 16.5-0.75+1.25g=21
 16.5+0.5g=21
 0.5g=21-16.5
 g=4.5/0.5
 g=9 <span>Golden Delicious apples
</span>
 6. If you also want to know the value of "d", you can substitute g=9 into the equation (i) and clear "d":

 d+g=22
 d+9=22
 d=22-9
 d=13 <span>Delicious apples

 How many Golden Delicious apples did Mary buy?

 The answer is: Mary bought 9 Golden Delicious apples.

Henry works at a warehouse where he earns $23.56 per hour. How much money will Henry earn after working for 37 hours and 42 minu
Burka [1]

Answer:

$888.21

Step-by-step explanation:

We'll break this problem into two chunks.

First, find the number of dollars Henry gets after working for 37 hours. Since he gets paid $23.56 per hour, all you do is multiply how many hours he's worked (37) by the rate he gets paid (23.56) which gets you $871.72.

Second, adding 42 minutes onto the 37 hours. Since there are 60 minutes in one hour, all you have to do is divide 42 minutes by 60 minutes to get how much of 42 minutes is 1 hour, which is 0.7. Multiply 0.7 by 23.56 (the rate he gets paid per hour) and you have $16.49.

Adding the two sums gets you 888.21 dollars in total.

Renting a truck costs $55.00 per day and $0.38 per mile when the driver goes beyond the 40 free miles allotted. How much would S
solmaris [256]
Well we need to multiply 55 by 2 because of the 2 days of renting. 55 * 2 = 110. Now we need to subtract 40 from 94 to find how many miles Samantha drove over 40. So 94 - 40 = 54. Now we need to multiply 54 by 0.38 to get the cost Samantha has to pay. 54 * 0.38 = 20.52. Finally we need to add the cost of 2 days of renting to the cost of the additional miles. 110 + 20.52 = 130.52. The total that Samantha has to pay for the truck is $130.52
I hope this was helpful and if so, please leave a good rating and thanks and maybe even brainliest answer. Thank you I really appreciate it. Have a nice day!

A charges les than B when m > 6
