Answer:
Since in this option the minute is paid at $0.40, the best option is 10 minutes for $ 4.
Step-by-step explanation:
Since four friends, Abe, Bob, Carl, and Darrel, are going to a fun park, and they want to ride go-karts, and the price to ride the go-karts is $ 2.15 for 5 minutes, $ 4.00 for 10 minutes, or $ 6.75 for 15 minutes, to determine which price is the best deal, the following calculations must be performed:
2.15 / 5 = 0.43
4/10 = 0.40
6.75 / 15 = 0.45
Therefore, since in this option the minute is paid at $ 0.40, the best option is 10 minutes for $ 4.
Answer:
it is C. An = 2(2)^n
Step-by-step explanation:
It will take 14.5 days or 15 days (rounded off)
Step-by-step explanation:
- Step 1: Given that the total money to be raised = $174. Money set aside of their profit = $12. Find number of days taken to raise this money
Number of days that will be taken = 174/12 = 14.5
∴ It will take 15 days (rounded off)
4x+7y=47 /*4 ------>16x + 28y=188
5x-4y=-5 /*7 -------->35x-28y=-35
16x + 28y=188, add this two equations
35x-28y=-35
16x + 28y+35x-28y=188-35
16x +35x=188-35
51x =153m
x=3
5x-4y=-5
5*3-4y=-5
15-4y=-5
4y=15+5
4y=20
y=5
Answer (3,5), B
