Answer: The loss percentage per gallon is 23.17%
Step-by-step explanation:Original price per gallon is $ 2.59
Discounted price per gallon is $ 1.99
Now, we will calculate the percentage loss per gallon, using the Direct Rule of Three as follows:
Price Percentage
2.59 100
1.99 x*****************************
2.59 * x = 1.99 * 100
2.59x = 199
x = 199/2.59
x = 76.83
So the percentage loss = 100 - 76.83
The percentage loss is 23.17%
Begin by creating a system of equations: let 'a' represent the amount Mary earns per student, and 'b' denote her fixed amount. The equations are 90=15a+b (subtracting the lower from the upper equation) and 62=8a+b. From these, we have 90-62=28, leading to 15a-8a=7a, and b cancels itself out. This gives us 7a=28, resulting in a=4. Substituting 'a' into 62=8a+b reveals b=30. Since Lisa earns half of Mary's base, her fixed amount is 15, but she makes twice as much per student, bringing her rate to 8 per student. Thus, we can formulate: m=4c+30 for Mary's earnings, and l=8c+15 for Lisa's. Setting c=20 results in m=110 and l=175, showing that Lisa makes more when teaching a class of 20 students. I trust this information helps.
Detailed explanation:
Thus,
100% plus 8% equals 108%
108% equals 1215
1% corresponds to 11.25
Therefore, 100% amounts to 1125 rs
It begins at 1.2 feet. In mathematics, dilation implies resizing, thus I will provide both possible results. Confirm with your teacher the expectation of the question. For enlargement, 1.2 * 2.5 equals 3, and for reduction, 1.2 divided by 2.5 equals 0.48.
