Question

1. At a coffee shop, a 16 ounce bag of coffee is on

sale at $5.25 less than the regular price. The cost
of 4 bags of coffee at regular price is the same as
the cost of 6 bags of coffee at sale price. Letr be
the regular price of coffee and s be the sale price
of coffee. Which of the following systems of
equations can be used to find the values of
variables r and s?

Answer 1

s = r - 5.25

4r = 6s

Explanation:

s = the sale price of the coffee

r = the regular price of the coffee
s = r -5.25 : sale price of the coffee equal the regular price minus 5.25 (on sale)

4r = 6s : 4 bags of regular coffee equals 6 bags at sale price
