Kevin is a server at an all-you-wish-to eat sushi restaurant. At one table, the customers ordered 3 child meals and 2 adult meals, which cost $80 in total. At another table, the customers ordered 5 child meals and 3 adult meals, which cost $125 in total. How much does each child meal and adult meal cost?

Read below for full answer :)

Step-by-step explanation:

We can conclude that the total cost of all meals was $205.

There were a total of 8 kids meals and 5 adult meals.

You'd have to divide 205 by 8, and you'd get 25.625.

Then, divide 205 by 5, and you'd get 41.

For example, we could say that each childrens meal was $15 ($120 total in kid's meals), and each adult was $17 ($85 total in adult meals).

When you total $85 and $120, it then given you a sum of $205.

There are many ways to complete this equation, but i feel that this is the easiest way.

Hope this helps! :)

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
