Answer: the group rented 11 Person tubes and 4 cooler tubes
Step-by-step explanation:
There are two types of tubes, Person tube and cooler tube.
Let P represent number of Person tubes that the group rented.
Let C represent number of Cooler tubes that the group rented.
The group spends $270 to rent a total of 15 tubes and Person tube $20 Cooler tube $12.50. Two linear equations can be derived from the above information
P + C = 15 - - - - - - - 1
20P + 12.5C = 270 - - - -- - - 2
Substituting P = 15 - C into equation 2,
It becomes
20(15-C) + 12.5C = 270
300 - 20C + 12.5C = 270
- 20C + 12.5C = 270 -300
7.5C = - 30
C = 30/7.5 = 4
P = 15 - C
P = 15 - 4 = 11
10 percent of 11.50 is 1.15. Subtract that from 11.50 and you would get 10.35. The sale price would be $10.35
Bob's Bikes
260 × 0.2 = 52
260 - 52 = 208
208 × 2 = $416.00
Walt's Wheels
300 × 0.6 = 180
300 - 180 = 120
120 × 2 = $240.00
Carson's Cycles
310 × 0.1 = 31
310 - 31 = 279
279 × 2 = $558.00
(i can't read what it says for $50, comment below if it makes a difference, i'll edit)
Tino's Transportation
260 ÷ 2 = 130
260 + 130 = $390.00
B) Walt's Wheels provides the lowest price for two bicycles.
