Question

Ms. Yost has 20 boxes of markers. Next year, she plans to buy 420% more boxes. How many boxes will she have in all?​

Answer 1

Answer:

Ms. Yost will have exactly $\blue{\bold{104}}$ boxes of markers.

Step-by-step explanation:

• We are given an initial value (20 markers) and an increase of that amount (420%).
• We can convert the percentage to a decimal and then multiply this by the initial value of markers.

We divide the percentage by 100 in order to find the decimal form of it.

If we wanted to find the percentage form of a decimal, we would multiply that value by 100 instead of dividing by 100.

$\begin{gathered}\frac{420\%}{100}=4.20\\\\20 \times 4.20 = \bold{84 \ boxes \ of \ markers}\end{gathered}$

Therefore, Ms. Yost will have 84 boxes of markers in total after increasing her original 20 boxes by 420%.

Finally, because she increased her total by 84 boxes, we need to add the initial amount as well.

20 + 84 = 104

As a final result, Ms. Yost will have exactly 104 boxes of markers.
