Step-by-step explanation:
All you need to do is look at the numbers given in the word problem and convert them to algebraic terms.
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.
