Question

ally bought a mattress and 4 pillows. the mattress cost $769 more than the 4 pillows. she gave the cashier $1300 and received $51 change. how much did each pillow cost?

Answer 1

Answer:

$60 per pillow ($240 for 4 pillows)

Step-by-step explanation:

let x be the mattress and y be one pillow.. then

x+4y=1300-51

x=4y+769

cost of one pillow

4y+769+4y=1249

8y=1249-769

y=480/8

y=$60 - cost of one pillow

cost of mattress is

x+4(60)=1249

x=1249-240

x=$1009 - cost of mattress
