The total cost of the computer, the juicer and the sandwich maker is $1500. The sandwich maker costs four times as much as the juicer. The computer costs twice as much as the total price of the sandwich maker and juicer. How much less does the sandwich maker cost than the computer?
| Sandwich Maker |
Juicer |
Computer |
| 4 u |
1 u |
|
| 5 u |
10 u |
| 4 u |
1 u |
10 u |
Cost of the juicer = 1 u
Cost of the sandwich maker = 4 u
Total cost of the juicer and the sandwich maker
= 1 u + 4 u
= 5 u
Cost of the computer
= 2 x 5 u
= 10 u
Total cost of the sandwich maker, the juicer and computer
= 10 u + 1 u + 4 u
= 15 u
15 u = 1500
1 u = 1500 ÷ 15 = 100
Amount that the sandwich maker cost less than the computer
= 10 u - 4 u
= 6 u
= 6 x 100
= $600
Answer(s): $600
