Answer:
50*0.1=5
Step-by-step explanation:
So 90% off of 50 looks like 50-90%. 50-90%=50*1-0.9*50 since 90% is 9/10 and we are doing 90 percent off of 50. 50*1-0.9*50=50*0.1=5. So $5.

Answer:
40 cars
Step-by-step explanation:
The total percentage of Ariana's car collection should be = 100%
35% of the collection = 14
1 percent = 14/35
1 percent is therefore 0.4
To get the total number of cars in Ariana's collection, we multiply 100 by 0.4
= 100 x 0.4 = 40
Therefore the total number of cars in her collection is equal to 40 and this is the answer to the question.
Another way to solve this is by cross multiplication
35% = 14
100% = ?
When we cross multiply we have:
(100x14)/35
= 1400/35
= 40
