Answer:
1448 mL
Step-by-step explanation:
The mass is the same.
Formula
m = d*V
Givens
<em><u>Olive Oil</u></em>
d = 0.92 grams / mL
V = ??
<em><u>Gasoline</u></em>
d = 0.74 grams / mL
V = 1.8 L = 1.8 L * (1000 ml / L)
V = 1800 mL
Solution
0.74 * 1800 mL = 0.92 * x Divide both sides by 0.92
0.74/0.92 * 1800 mL = 0.92 *x / 0.92 Combine the left
0.8043 * 1800 mL = x
x = 1448 mL
The volume of Olive Oil needed is 1448 mL
Answer:
$30.72
Step-by-step explanation:
You were right with your answer, the teacher is probably just wanting you to tip on the subtotal (before tax) instead of the total total. Instead of doing total+tax+tip, we're going to figure out the tax and tip separately and then add it all together.
<u>Tipping on the subtotal (what your teacher wanted)</u>
20% of $24 = $4.80
8% of $24 = $1.92
$24+$4.80+$1.92=$30.72
<u>Tipping on the total (what you did)</u>
8% of $24 is $1.92
New total is $25.92
20% of $25.92 is $5.18
$25.92 + $5.18 = $31.10
