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.

1 answer:

5 0

If the profit was 170 then 25 things were bought. since n is 25 you multiply it by 8 which is 200 and if you then subtract 30 the answer is 170

Answer:

52/79

Step-by-step explanation:

One costume = 156 (This is our numerator.)

All visitors = 156 + 58 + 23 = 237 (This is our denominator.)

156/237

Find the GCF to simplify (sneak peek it's 3)

156/3 = 52

237/3 = 79
