0.06x=0.045(65100-x)+231
Solve for x
X=30100
Find the amount of interest in each account
0.06(30100)=1806 first account
0.045(65100-30100)=1575 sec account
Total interest=1,806+1,575=3,381

a lunch stand makes a $.75 profit on each chef's salad and $1.20 profit on each caesar salad. On a typical weekday, it sells bet
tangare [24]

Answer:

<em>50 Chef's salads and 50 Caesar salads should be prepared in order to maximize profit.</em>

Step-by-step explanation:

Suppose, the number of Chef's salad is x and the number of Caesar salad is y

On a typical weekday, it sells between 40 and 60 Chefs salads and between 35 and 50 Caesar salads.

So, the two constraints are:  40\leq x\leq 60 and  35\leq y\leq 50

The total number sold has never exceed 100 salads. So, another constraint will be:   x+y\leq 100

According to the graph of the constraints, the vertices of the common shaded region are:  (40,35), (60,35), (60,40), (50,50) and (40,50)   <em>(Refer to the attached image for the graph)</em>

The lunch stand makes a $.75 profit on each Chef's salad and $1.20 profit on each Caesar salad. So, the profit function will be:  P=0.75x+1.20y

For  (40, 35) ,   P=0.75(40)+1.20(35)=72

For  (60, 35) ,   P=0.75(60)+1.20(35)=87

For  (60, 40) ,   P=0.75(60)+1.20(40)=93

For  (50, 50) ,   P=0.75(50)+1.20(50)=97.5 <u><em>(Maximum)</em></u>

For  (40, 50) ,   P=0.75(40)+1.20(50)=90

Profit will be maximum when x=50 and y=50

Thus, 50 Chef's salads and 50 Caesar salads should be prepared in order to maximize profit.

Casey needed to move 23 huge boxes from his truck to the loading dock. His forklift could only hold three boxes at once. How man
miss Akunina [59]

Answer:

8

Step-by-step explanation:

Since the forklift has a maximum capacity of three boxes per trip, simply divide the total number of boxes (23 boxes) by three and round up to the nearest whole unit to find the number of trips required:

n=\frac{23}{3}=7.667

Casey had to visit the dock 8 times. He moved three boxes in seven trips and two boxes in one trip.

Helps pls HELPPPPPPP
Brrunno [24]

Answer: Third option.

Step-by-step explanation:

Let be "x" the approximate actual width  (in feet) of the car.

Based on the information provided in the exercise, you know that the scale of the model car is this one:

1:32

Which can be written as a fraction:

\frac{1}{32}

Therefore, if you know that the width of the model car is 2.3 inches, you can set up the following proportion:

\frac{1}{32}=\frac{2.3}{x}

Finally, you must solve for "x" in order to find its value.

So you get the following result:

(x)(\frac{1}{32})=2.3\\\\x=(2.3)(32)\\\\x=73.6
