QuestionMariko and her friend spent \$24.50 on lunch with a \$4 coupon. Find the cost of each lunch.

Studdy Solution

STEP 1

Assumptions1. The total cost of lunch for Mariko and her friend is $24.50. The cost of each lunch is the same3. They used a$ 4 off coupon4. The coupon is applied to the total cost of the lunches, not each individual lunch

STEP 2

First, we need to find the total cost of the lunches before the coupon was applied. We can do this by adding the value of the coupon to the total cost after the coupon was applied.
$Total\, cost\, before\, coupon = Total\, cost\, after\, coupon + Coupon\, value$

STEP 3

Now, plug in the given values for the total cost after the coupon was applied and the coupon value to calculate the total cost before the coupon was applied.
$Total\, cost\, before\, coupon = \$24.50 + \$$

STEP 4

Calculate the total cost before the coupon was applied.
$Total\, cost\, before\, coupon = \$24.50 + \$4 = \$28.50$

STEP 5

Now that we have the total cost before the coupon was applied, we can divide this by the number of lunches (2) to find the cost of each lunch.
$Cost\, of\, each\, lunch = Total\, cost\, before\, coupon / Number\, of\, lunches$

STEP 6

Plug in the values for the total cost before the coupon was applied and the number of lunches to calculate the cost of each lunch.
$Cost\, of\, each\, lunch = \$28.50 /2$

STEP 7

Calculate the cost of each lunch.
$Cost\, of\, each\, lunch = \$28.50 /2 = \$14.25$ The cost of each lunch is $14.25.
