Question

Gail is selling Girl Scout cookies. This week Mrs. Martin bought 3 boxes, Mr. Leesville bought 4 boxesm, and her friend Carroll bought 1 box. Mr. Millbrook cannot eat cookies so he gave a $7 donation to Gail's troop. If Gail sold 10 boxes last week and the amount of money she collected last week equals the amount of money she collected this week, write and solve an equation to determine how much each box of cookies costs.

Answer 1

Let's assume that the cost of each box of cookies is "x" dollars.

Based on the given information, Gail sold a total of 3 + 4 + 1 = 8 boxes of cookies this week, and Mr. Millbrook gave a $7 donation. Therefore, the total amount of money collected this week is:

8x + 7

Since we know that Gail sold 10 boxes of cookies last week and collected the same amount of money, we can set up an equation:

10x = 8x + 7

Solving for x, we get:

2x = 7

x = 3.50

Therefore, each box of Girl Scout cookies costs $3.50.
