Answer:
$17.12
Step-by-step explanation:
First let's find the normal cost with tax
7/100*19=133/100=$1.33
$19+$1.33=$20.33
Now we find the cost with tax for the Valentine's Day price
7/100*35=$2.45
$35+$2.45=$37.45
Now we subtract the normal cost from the Valentine's Day price
$37.45-$20.33=$17.12
<u>Answer:</u>
Nadia's total earnings in month is $3196.1
<u>Explanation:
</u>
Given salary of Nadia is $3,300 per month including a 3.25% commission

x = 
x = $3196.1 per month
Therefore, the fixed salary of Nadia is $3196.1 per month
