Ariana has atoy car collection. She keeps 14 of the toy cars on her wall, which is 35% of her entire collection. What is the tot
Flauer [41]

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

Thank you!

What is the sales tax on a breakfast order that totals $10.50 when tax is 5%
Alecsey [184]
First, you would need to create an equation for this problem. Let x represent the unknown tax. 
\frac{x}{10.50} = \frac{5}{100}

Next, you would cross multiply. 
100x = 52.5

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100. 
x = $0.525

I hope this helps!
