Problema Solution
please solve: A 3 - pound bag of potato's cost $1.35. at that rate, what would a 4 - pound bag of potato's cost? thank you, Ray
Answer provided by our tutors
set up a proportion relating the amount of pounds to the cost:
3/1.35 = 4/x
cross multiply to solve for x, where x is the price of a 4-lb bag of potatoes
3x = 5.40
x = 1.80
Therefore, a 4-pound bag of potatoes costs $1.80
