the last one is the answer!
Answer:
Jamal :
have = $18
need = $46-$18
= $28
saves = $5 each week
= $5 × 5 weeks
= $25 ( not enough )
Samuel :
have = $10
need = $46 - $10
= $36
saves = $7 each week
= $7 × 5 weeks
= $35 ( not enough )
thus, both boys would not have enough money to pay for the trip .
105/23727.90=100/x
105x=23727.90x100
105x=2372790
(105x)/105=2372790/105
x=22598
dealers cost is $22,598
the 105% is the 100% price of the car plus the 5% of that tax or whatever it is
In 5 years, the price increased about 30%.
