c. 35 + 50x ≤ 1,325

Step-by-step explanation:

Abbey's total cost must be less then or equal to her total savings, i.e.

cost ≤ savings

it is given that cost = fixed registration fee and a monthly fee of $50 per month. Hence,

fixed registration + (monthly fee)*(number of months) ≤ savings

let the number of months be x,

hence

35 + 50x ≤ 1325(c)

Answer:

$c=\dfrac{27}{40}\\$

Step-by-step explanation:

We are required to solve for c in the equation: $\dfrac{1}{8}+c= \dfrac{4}{5}$

Step 1: Collect like terms

$\dfrac{1}{8}+c= \dfrac{4}{5}\\c= \dfrac{4}{5}-\dfrac{1}{8}$

Step 2: Find the Lowest Common Multiple of the denominators

LCM of 8 and 5 is 40

Step 3: Multiply all through by 40

$40c= \dfrac{4}{5}*40-\dfrac{1}{8}*40$

Step 4: Simplify

40c=32-5

40c=27

Step 5: Divide both sides by 40 and simplify if possible.

$c=\dfrac{27}{40}\\$

What fraction is equivalent to four tenths and has a denominator of 100?

Sever21 [200]

Answer:

$\frac{40}{100}$

Step-by-step explanation:

You can multiply on the upper and bottom part by the same number without changing the fraction so $\frac{4}{10}=\frac{4\cdot 10}{10\cdot 10}=\frac{40}{100}$
