A store sold 9 guitars for a total of $3611. Electric guitars sold for $479 each and acoustic guitars sold for $339 each. How many of each type of guitar were s

Question

the last part says sold. I need to identify each variable. Also I need it to be written like a system of equations then solve the problem 

Answer 1

E + A = 9

 

479E + 339A = 3611

 

479E + 339( 9 - E) = 3611

 

 

479E + 3051 - 339E = 3611

 

140E = 3611 - 3051

 

140E = 560

 

E = 4

 

A=5

 

5 acoustic, 4 electric
