Answer 1

$53.5

Explanation:

In this problem, you need to find the price of a single hamburger and a single drink. Sadly, you only have the total cost. Thus, there is no way to solve the problem...

Jk

You just need some math. Let's represent hamburgers as x and Drinks as y. You get two equations from customer one.

• x+y=6;

• 2x+4y=$13.00

Next, we need to isolate one of the variables. Let's start with the easiest equation, which is the first.

1. x+y=6
2. x=6-y. (We subtracted y by both sides to isolate the x variable.)

Now, we know what x equals. Let's plug that into the next equation and solve.

1. 2x+4y=$13.00 (Original equation.)
2. 2(6-y)+4y=$13 (Substituted x)
3. 12-2y+4y=$13 (Multiplied 2 by 6-y)
4. 2y=$1 (Isolated the variable)
5. y= $0.5 (Reduced.)

Now we know a drink costs $0.50, which is 50 cents. Now, let's use that information to solve the first problem.

1. x+y=6
2. x+0.5=6
3. x=$5.5

Thus, a hamburger costs $5.5. Now, let's solve for the problem.

1. 8y+9x=?
2. 8(0.5)+9(5.5)
3. 4+49.5=53.5

Therefore, you expect to pay $53.5
