Question

Kenny ordered guitar strings for Glenn’s Guitar Shop. The premium guitar strings are $4.50 apiece. The standard guitar strings are $1.50 apiece. The bill smeared in the rain, but Kenny knows he ordered a total of 80 strings for $225. Kenny wants to solve for the number of each type of string, so he represents variables as shown. Let x = the number of premium strings. Let y = the number of standard strings.

Answer 1

The equation for the total number of strings ordered is

X+Y=80

The equation based on the price of each type of string and the total value of the order is

4.50 x +1.50 y = 225

Correct me if I'm wrong,

happy to help!
