Question

the formula p= 8n - 30 gives the profit p when a number of items n are each sold at $8 and expenses totaling $30 are subtracted. If the profit is $170.00, how many items were bought?

Answer 1

Answer:

25 items were bought.

Step-by-step explanation:

Given the formula of profit :

$p = 8n - 30$

Where: n = number of items sell at the price $8 each

If the profit is $170.00, then n items will be:

p = 170.00

$p= 8n - 30$

$170.00=8n-30$

$n=\frac{170.00+30}{8}=25$

25 items were bought.

Answer 2

170=8n-30
Just need to solve for n.
200=8n
25=n
