Question

You were billed $17.60 for water usage at a rate of $0.55 per gallon. Three choices are correct ways to calculate the the number of gallons, g, of water that you used. Which choice is NOT?

a) 17.6 = 0.55 • g

b) 17.60/55 = g

c) 0.55g = 17.6

d)0.55/g = 17.6

Answer 1

Looks like a typo in b). Should it be 17.60/0.55 = g ?

Answer 2

basically the correct way would be to divide 17.60 by 0.55 to calculate the number of gallons used.
(a) 17.6 = 0.55g ....to solve this, you would divide both sides by 0.55
1.7.6/0.55 = g (this is correct)
(b) 17.60/0.55 = g (this is correct as well)
(c) 0.55g = 17.6...you would divide both sides by 0.55
g = 17.6/0.55 (this is correct)
(d) 0.55/g = 17.5.....to solve this, you would multiply both sides by g
0.55 = 17.5/g (incorrect)

ahh okay, thank you
