Andrej [43]

Sophia has $ 1912.03 left from last month's earnings

<u>Solution:</u>

Given, sophia earned $2,000 last month.  

She used 35 of her earnings to pay her bills.  

With the remaining money, she bought two shirts for $19.99 each and a pair of earrings for $12.99.  

We have to find how much money does Sophia have left from last month's earnings

Now, we know that,  

<em>Left money = earned money – used money</em>

= 2000 – (bills paid + 2 shirts cost + 1 pair of ear rings)

= 2000 – (35 + 2 x 19.99 + 12.99)

= 2000 – (35 + 39.98 + 12.99)

= 2000 – (87.97) = 1912.03

Hence, Sophia has $ 1912.03 left with her.
