Answer:
125 packages of chips.
Step-by-step explanation:
A vending machine sells chips at $0.55
And candy at $0.75
Last month, the vending machine yielded $170.00 with the sale of 260 items.
Let x be the number of chips sold and y be the number of candies sold.
$0.55x + $0.75y = $170.00
x + y = 260
Solving the above simultaneous equations by substitution;
x = 260 - y
Then,
0.55(260 - y) + 0.75y = 170
143 - 0.55y + 0.75y = 170
0.2y = 170 - 143 = 27
y = [tex]\frac{27}{0.2}[/tex] = 135
x = 260 - 135 = 125
So there were 125 packages of chips sold.
