for 3 hours, both studios charge the same amount.
The cost equation for studio A is:
A(x) = 10.49 + 8*x
The cost equation for studio B is:
A(x) = 14.99 + 6.5*x
The cost will be the same when A(x) = B(x), then we just need to solve the linear equation:
10.49 + 8*x = 14.99 + 6.5*x
8x - 6.5x = 14.99 - 10.49
x = (14.99 - 10.49)/(8 - 6.5) = 3
This means that for 3 hours, both studios charge the same amount.
