ANSWER
$59.55
EXPLANATION
We have that Julio is paid 14% of his first $120 of sales and 19% of any sales more than $120.
He sold $345 worth of cookies last month.
To find the amount his gross paycheck will be, we have to partition the money he earned that month since he is paid in 2 parts.
We have to find out how much more than $120 he made:
$345 - $120 = $225
Now, we will find 14% of $120 and 19% of $225:
[tex]\begin{gathered} \frac{14}{100}\cdot\text{ 120 = \$}16.80 \\ \frac{19}{100}\cdot\text{ 225 = \$}42.75 \end{gathered}[/tex]Now, we find the sum:
Gross Paycheck = $16.80 + $42.75
Gross Paycheck = $59.55
His gross paycheck that month will be $59.55
