1. The Yeoman family spent a total of $26.75 on lunch. They bought 5 drinks and 3 sandwiches. Each drink costs $2.50 less than a sandwich. Which of the following equations could be used to find the cost of each sandwich?

a. 26.75 = 5 (2.50) + 3s

b. 26.75 = 3 (2.50) + 5s

c. 26.75 = 5s + 3 (s + 2.50)

d. 26.75 = 3s + 5 (s - 2.50)

2. Solve the equation for a rounded to the nearest tenth:

3a - 0.3 (a + 50) = 75

Frederick Pratt · Answer 1

1. 26.75 = 3s + 5 (s - 2.50)

2. 3a - 0.3 (a + 50) = 75

3a - 0.3a - 15 = 75

3a - 0.3a = 75 + 15

2.7a = 90

a = 90/2.7

a = 33.3 <===
