Answer: 10
Step-by-step explanation:
Given that:
Amount charged per car detailed = $155
Amount required to rent apartment :
Application fees = $125
Securiry deposit = $890
first and last month rent = 2 × $1100 = $2,200
Total amount required to rent apartment :
$(125 + 890 + 2200) = $3,215
Amount in saving = $1,763
Additional amount needed :
$3215 - $1763 = $1452
Number of cars needed to detail in other to have enough to rent apartment :
Additional amoint required / amount charged per car detailed
$1452 / $155
= 9.36
Hence, he must detail 10 cars in other to have enough money
