Answer 1

The number of subscriptions she sell in three days is 34. The calculation is done by dividing the money earned with the rate per subscription.

What is division?

Division is one of the four basic operations in math. It is used to calculate the number of small units that can be obtained from a larger unit. In the given question, the amount of earning is divided by the rate per subscription to calculate the number of subscriptions sold.

Calculation:

Given:

$\begin{aligned} \rm Rate\:per\:subscription &= \ 5.35\\ \\ Money\: earned\: on\: Monday &= \ 42.80\\ \\ Money\:earned\:on\:Tuesday &= \ 64.20\\ \\ Money\:earned\:on\:Wednesday &= \ 74.90\\ \\ Total\: money\: earned \:in \:three \:days &= \ 42.80 + \ 64.20 +\ 74.90\\\\ &=\ 181.90\end$

Therefore, number of subscriptions sold in three days will be:

$\begin{aligned} \rm Number\:of\:subscriptions &=\rm \dfrac{Total\:money\:earned}{Rate\:per\:subscription}\\ \\ \rm Number\:of\:subscriptions &= \dfrac{181.90}{5.35} \end$

Hence the number of subscriptions Erica sell in three days is 34.
