PLEASE HELP !!!

Mathematics
1 answer:

Answer:

final cost of 3 pounds: <u>  8 dollars  </u>

final cost of p pounds: <u>   3.75p - 3.25  dollars  </u>

Step-by-step explanation:

Each pound costs $3.75, so 3 pounds cost 3*3.75 = 11.25 dollars. Subtract off the $3.25 to get the final cost to be 11.25-3.25 = 8 dollars. This takes care of the first part.

For the second part, the expression for the final cost is 3.75p - 3.25; where the 3.75p is the cost before the coupon is applied. If you plugged p = 3 into that expression, you should get 8 as a result. The variable p is some positive whole number. It's a place holder for the number of pounds of apples.
