Henry needs to sale 14 rings for his revenue to equal his expenses.
Step-by-step explanation:
Given,
Selling price of ring = $8
Expense on one ring = $1.50
Cost of supplies = $91
Let,
x represent the number of rings.
Expenses = 91+1.50x
Revenue = 8x
Equal expenses means;
Revenue = Expenses
[tex]8x=91+1.50x\\8x-1.50x=91\\6.5x=91[/tex]
Dividing both sides by 6.5
[tex]\frac{6.5x}{6.5}=\frac{91}{6.5}\\x=14[/tex]
Henry needs to sale 14 rings for his revenue to equal his expenses.
