Answer:
D
Step-by-step explanation:
7 * 12 = 84
And 1/4 hours which is 7/4 which is $1.25 more.
So she got 85.25 dollars in total, which is a little less than $90.
We can use prime factorization to find the GCF:
The greatest value both 12 and 20 share is 4. By factoring this out of the equation, we get:
4(3 + 5) = 4(8) = 32
23 1/2
The first one is 10^-5 and the second one is 10^5.
