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.

What is the simplified form of the equation 4/5n - 1/5 = 2/5n ?
Gnoma [55]

we are given

\frac{4}{5}n -\frac{1}{5} =\frac{2}{5}n

Firstly , we will multiply both sides by 5

5*\frac{4}{5}n -5*\frac{1}{5} =5*\frac{2}{5}n

now, we can simplify it

4n-1 =2n

2n =1

now, we can solve for n

n =\frac{1}{2}.............Answer
