Santa Claus has been experiencing some recent back pain and is unable to carry large bags of toys over his shoulders. As a result he uses redex to deliver many of his gifts this year. Fedex charges a flat rate of $2.50 plus $0.85 per pound. If the cost of sending gifts to the Jones is $28.85, how much did their gifts weigh?

31 pounds

Step-by-step explanation:

From the question, we are informed that Fedex charges a flat rate of $2.50 plus $0.85 per pound and that the total cost of sending gifts to the Jones is $28.85. This can be mathematically expressed as:

2.50 + 0.85p = 28.85

where p = weight of the gift

So we have to solve the equation

2.50 + 0.85p = 28.85

0.85p = 28.85 - 2.50

0.85p = 26.35

p = 26.35/0.85

p = 31

Therefore the weight of the gift is 31 pounds
