Maria sold 28 skateboards over the weekend at her toy store. this was 30% of all the skateboards she had in stock. how many skateboards were in stock?

Answer : 93 skateboards were in stock approximately.

Step-by-step explanation:

Concept of Percentage: by a certain percent, we mean how many hundredths.

Thus, x percent means x hundredths, written as x%

To express x% as a fraction: we have, x% = x/100

If we call S, the number of skateboards that we had in stock, and now they tell us that we have sold 30% of that amount, which were 28 units, this means:

S · 30/100 = 28 units

Then, S = 28·100/30 = 2,800/30 = 93.33 => aprox. 93 units

Answer : 93 skateboards were in stock approximately.

Verification:

We can calculate 30% of 93 skateboards

93 · 30/100 = 27.9 approximately = 28 skateboards
