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?

Respuesta :

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

Answer:

25 items were bought.

Step-by-step explanation:

Given the formula of profit :

[tex] p = 8n - 30 [/tex]

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

[tex]p= 8n - 30 [/tex]

[tex]170.00=8n-30[/tex]

[tex]n=\frac{170.00+30}{8}=25[/tex]

25 items were bought.
