So they bought x half gallons at $1.35 each ($2.70 per gallon). so their cost was:
C = 1.35x
Their revenue was the remainder of the milk (x - 13 that ruined) times the price:
R = 4.04(x - 13) = 4.04x - 52.52
The profit is Revenue - Cost
P = R - C = 4.04x - 52.52 - 1.35x = 2.69x - 52.52
Now we know they made 62.72 profit, so:
2.69x - 52.52 = 62.722.69x = 115.24x = 42.84 or about 43 half gallons
Answer:
123
Step-by-step explanation:
To solve this question,
you can use BODMAS THEORY
That means,
B - brackets
O - of
D - division
M - multiplication
A - addition
S - subtraction
Now you can solve the sum like this.
13 + 11 × 10
13 + 110
= 123
Hope this helps you.

Answer:
10.5%
Step-by-step explanation:
The tangent of the angle is the ratio of rise to run.
tan(angle) = grade
tan(6°) ≈ 0.105 = 10.5%
The grade will be 10.5% for an angle of elevation of 6°.
Answer:
(c) $80
Step-by-step explanation:
Each discounted price corresponds to the original price multiplied by a factor related to the discount. For a discount fraction of 'd', the multiplier is (1 -d).
This means you can use any of the lines in the table to find the original price.
<u>5% disount</u>: (1 -5%)·p = $76 . . . . where p is the original price
p = $76/0.95 = $80 . . . . . . . the original price
<u>10% discount</u>: (1 -10%)·p = $72
p = $72/0.90 = $80
<u>25% discount</u>: (1 -25%)·p = $60
p = $60/0.75 = $80

<em>Additional comment</em>
The table values for 5% and 10% differ by 5% and $4. That means 5% of the original price is $4. There are two things you can do with this:
- add back that 5% to the 5%-discounted price: $76 +4 = $80
- multiply that 5% by 20 to get 100% of the original price: 20(5%) = 20($4) ⇒ 100% = $80.
