Avending 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 the number of candies. how many packages of chips were purchased last month

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 = = 135

x = 260 - 135 = 125

So there were 125 packages of chips sold.

step-by-step explanation:

in a an geometric explicit equation, the first number is the starting rate. in this case 10.

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )
