Answer:
x+y=80 and 5x+10y=650 system of equations can be used to solve for the number of shirts sold.
Explanation:
Given that:
Cost of each cap = $5
Cost of each shirt = $10
Total amount made = $650
Total caps and shirts sold = 80
Let,
x be the number of caps sold
y be the number of shirts sold.
According to given statement;
x+y=80
5x+10y=650
Hence,
x+y=80 and 5x+10y=650 system of equations can be used to solve for the number of shirts sold.
