Popsicles cost $0.80, and ice cream cost $0.65. If you purchased 9 items for $6.15, how many of the items were popsicles?
Answer provided by our tutors
let
x = the number of popsicles, x>=0
y = the number of ice creams, y>=0
you purchased 9 items for $6.15:
x + y = 9
0.80x + 0.65y = 6.15
by solving the above system of equations we find:
x = 2 popsicles
y = 7 ice-creams
