Question

9 When determining what price to charge for a soda, Randy's restaurant uses $0.30 for the cup and $0.05 per ounce

of soda, s. Their pricing plan is represented by the expression: 0.30 +0.05 s.
How much would Randy's restaurant charge for an 18 ounce cup of soda?

Answer 1

$1.20

Explanation: y = $0.05x + 0.30.

y = $0.05(18) + 0.30 since the 0.30 is for the cup and 0.05 multiplied by how many ounces you have.

`0.05 * 18 = $0.90`

So, add 0.90 to 0.30 and it will give you the total cost for an 18 ounce cup.
