Answer: 7
Explanation: we need to solve for x which is the number of Artichokes
.8x (80-cents per artichoke) + 2(.95x) (twice as many pineapples at 95-cents) = 18.90 (total amount spent)
.8x + 1.9x = 18.90
2.7x = 18.90 (.8x + 1.9x = 2.7x)
x = 18.90/2.7 (divide both sides by 2.7 to get x)
x = 7
to check the solution
.8(7) + 2(.95*7) = 18.90
5.60 + 2(6.65) = 18.90
5.6 + 13.30 = 18.90
18.90 = 18.90
7 Artichokes
14 Pineapples (twice as many as Artichokes)
