Sales increased by only 12% last month. If the sales from the previous month were $152,850, what were last months sales

Tamiku [17]

Answer:

$\$171,192$

Step-by-step explanation:

Remember that

$100\%+12\%=112\%=112/100=1.12$

we know that

The sales from the previous month were $152,850

This amount represent the 100%

Find out what were last months sales, multiply the sales from the previous month by the factor 1.12

$\$152,850(1.12)=\$171,192$
