Question

Miguel created the ratio table below to show how he uses the money he earns at work. How much money will he save if he earns 120.00?

Answer 1

The money he will save if he earns $120.00 is $90.00.

Explanation:

Given:

In the figure is the ratio of the savings and the earnings.

Now, to find out that how much savings will be if Miguel earns $120.00.

We need to get the percentage of the ratio of the earning and saving.

So, according to the table:

If he earns $10.00 then he saves $7.50.

`(7.50)/(10)* 100`

`=0.75* 100`

`=75`

So, if Miguel earns $10.00 he save the 75% of it.

If he earns $50.00 then he saves $37.50.

As we calculate the percentage as the above process then the saving is 75% of the earning.

And, if he earns $150.00 and save $112.50 then it is also the 75% of the earning as mentioned above.

Now, to find the saving of the earning $120.00.

So, it will be 75% of the earning as we observe in the above case:

75% of $120.00

`(75)/(100)* 120`

`=0.75* 120`

`=90`

Therefore, the money he will save if he earns $120.00 is $90.00.
