Sandwich cost $7.70 and the soda costs $2.20.
4/10 x 0.04 = (of means multiply)
0.4 x 0.04 =
0.016
First we divide 102 by 12.75 to get the hours which is 8 hours. So it would take 8 hours
Answer:
$43.20
Step-by-step explanation:
To find the original purchase price, write a proportion and solve. A proportion is an equation where two ratios are set equal.
If the discount if 15% then you pay 85%.

To solve for y, cross multiply the numerator and denominator of each fraction.
36.72(100) = 85y
3672= 85y
43.2 = y
I believe the answer is: -190.98
