Answer:
a) total cost (C) = 22 s + 50 (b) s = (C - 50) / 22 (c) 80
Step-by-step explanation:
The equation for the cost is:
cost (C) = 22 s + 50 where s is the quantity of square yards purchased.
b) solve for s
C = 22 s + 50
C - 50 = 22 s
s = (C - 50) / 22
c) the amount of square yard that can be purchased by $ 1810
s = (1810 - 50) / 22 = 1760 / 22 = 80
