Answer:
Step-by-step explanation:
It is important to write a number as a product of primes because on many tests, you will be asked to write the "prime factorization". Also, any time you are asked a question about multiples or factors, you bet using prime factorization will get you your answer quicker!<span>

First you need to understand the structure of the commission.
The first part is 6% commission on sales up to $500.
The second part is 8% commission on sales over $500.
Note that the second part doesn't mean that a sale of $800 gets 8% of $800.
It means that once we have reached $500, any *further* sales get 8%.
Since $800 is $300 more than $500, the commission is
6% of $500 +
8% of $300
The first thing she did was work out the excess above $500.
Then she worked out the two percentages in two separate parts.
The second part seems to have incurred a cut and past accident, not sure if that is yours or it was already done.
Given that,
Total no of cards = 20
The ratio of animal cards to fruit cards is 2:3
No of animal cards = 20
Solution,
Let there are 2x animal cards and 3x fruit cards. ATQ,
2x+3x = 20
5x = 20
x = 4
Animal cards = 2x
= 2(4)
= 8
Fruit cards = 3x
= 3(4)
= 12
It is also mentioned that, of the cards, 1/3 have bananas on them. It means,
Hence, 4 cards have bananas on them.
Answer:
x=2
Step-by-step explanation: 2 squared = 4, 4*2 = 8, 8+-8=0
