Question

Alonso went to the store to buy some almonds. the price per pound of the almonds is $7.25 per pound and he has a coupon for $3.50 off the final amount. with the coupon, how much would alonso have to pay to buy 5 pounds of almonds? also, write an expression for the cost to buy pp pounds of almonds, assuming at least one pound is purchased.

Answer 1

7.25p-3.50

Step-by-step explanation:

Original cost = cost per pound x 5

= 7.25 x 5

= 36.25

final cost = original cost - coupon

= 36.25 - 3.50

= 32.75

Cost of p pounds

Original cost = cost per pound x p

= 7.25 x p

= 7.25p

coupon = 3.50

Final cost = original cost - coupon

= 7.25p - 3.50

Answer 2

Step-by-step explanation:

a+p = 10

5a+3p = 4.6(10)

a = 10-p

5(10-p) + 3p = 46

50-5p + 3p = 46

2p = 4

p= 2

a = 10 - 2 = 8
