Answer:
0.389x + 65.556
Explanation:
Given that :
Wage as nail technician = $5.50
Wage for hair = $9.00
Total wage earned = $590
Let :
number of hairs done = x
Number of nails fixed = y
To calculate the total appointment, y
5.50x + 9y = 590
Express y in terms x :
9y = 590 - 5.50x
Divide through by 9
y = (590 - 5.50x) / 9
y = 65.556 - 0.611x
x + y =?
x + 65.556 - 0.611x
0.389x + 65.556
