The final cost of 5 pounds would be calculated by multiplying the price per pound ($6.25) by the number of pounds (5) and subtracting the coupon amount ($3.25):
Final cost of 5 pounds = (Price per pound * Number of pounds) - Coupon amount
= ($6.25 * 5) - $3.25
= $31.25 - $3.25
= $28
Therefore, Mariana would have to pay $28 to buy 5 pounds of chicken.
To write an expression for the cost to buy p pounds of chicken, assuming at least one pound is purchased, we can use the same formula:
Final cost of p pounds = (Price per pound * Number of pounds) - Coupon amount
= ($6.25 * p) - $3.25
Mariana went to the store to buy some chicken. The price per pound of the chicken is $6.25 per pound and she has a coupon for $3.25 off the final amount. With the coupon, how much would Mariana have to pay to buy 5 pounds of chicken? Also, write an expression for the cost to buy p pounds of chicken, assuming at least one pound is purchased.
Final cost of 5 pounds:
Final cost of p pounds:
