EASY MATH!!! GIVING BRAINLIEST!!

musickatia [10]

Answer:

55

Step-by-step explanation:

So lets take our 50 dollars.

Next, take your increase of 5%. Remember, 5% is 0.05, and it is a increase of 5%, so we are multipling 50 by 1.05.

Before we start multiplying, lets recall that this occurs twice(2 years), but this doesnt mean we multiply 50 by 1.10. No, we just mutiply 50 by 1.05 2 times:

50*1.05

=

52.5

52.5*1.05

=

55.25

So your answer is 55 dollars(rounding down).

Hope this helps!

Question #2 What is the difference?

e-lub [12.9K]

Answer:

B $\frac{b-10}{b-1}$

Step-by-step explanation:

In order to get the same denominator, we need to multiply the second fraction by (b+2) in the numerator and denominator.

We will end up in something like this : $\frac{b^{2} - 2b - 8 -6(b+2) }{(b-1)(b+2)}$

I just timed the second fraction by b+ 2 and then i added them together.

Therefore, we will get $\frac{b^{2} - 8b - 20}{(b-1)(b-2)}$

now factoring the numerator we will end like this

$\frac{(b-10)(b+2)}{(b-1)(b+2)}$

we will then end up with the answer.

Hope this helps.
