The total cost of the television, the sandwich maker and the juicer is $400. The juicer costs four times as much as the sandwich maker. The television costs thrice as much as the total price of the juicer and sandwich maker. How much less does the juicer cost than the television?
| Juicer |
Sandwich Maker |
Television |
| 4 u |
1 u |
|
| 5 u |
15 u |
| 4 u |
1 u |
15 u |
Cost of the sandwich maker = 1 u
Cost of the juicer = 4 u
Total cost of the sandwich maker and the juicer
= 1 u + 4 u
= 5 u
Cost of the television
= 3 x 5 u
= 15 u
Total cost of the juicer, the sandwich maker and television
= 15 u + 1 u + 4 u
= 20 u
20 u = 400
1 u = 400 ÷ 20 = 20
Amount that the juicer cost less than the television
= 15 u - 4 u
= 11 u
= 11 x 20
= $220
Answer(s): $220
