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. Let x = the number of premium strings. Let y = the number of standard strings. X y = 80, 4. 50x 1. 50y = 225 How many of each type of string did Kenny order? He ordered premium strings. He ordered standard strings.

x = 35     y = 45

Step-by-step explanation:

Total number of strings:  x + y = 80  ⇒  x = 80 - y

Substitute  x = 80 - y  into  4.5x + 1.5y = 225  to find y:

4.5(80 - y) + 1.5y = 225

360 - 4.5y + 1.5y = 225

                      3y = 135

                        y = 45

Substitute the found value of y into  x + y = 80  to find x:

x + 45 = 80

x = 80 - 45 = 35

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
