Henry sells rings for $8 dollars each his expenses are $1.50 per ring plus $91 for supplies how many rings does he need to sell

Ne4ueva [31]

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

$8x=91+1.50x\\8x-1.50x=91\\6.5x=91$

Dividing both sides by 6.5

$\frac{6.5x}{6.5}=\frac{91}{6.5}\\x=14$

Henry needs to sale 14 rings for his revenue to equal his expenses.
