Okay. Let us do it surgically. Let us solve first the rate of increase in Lliana's Math grade. 86-65 = 21, thus the rate can be written as a fraction 21/65. We will reserve the decimal form once we are done with both rates of increase.
On the same note, Fiona's increase in Math grade is determined by subtracting 70 from her recent grade of 80, thus giving us an increase in her grade by 10. Therefore, the rate of increase in her Math grade is 10/70.
Now, let us take the decimal forms of the students' grade in math respectively. Lliana's is 21/65 or 0.32307692307... Fiona's is 10/70 or 0.14285714285. Now, subtracting this decimals we have 0.18021978021.
Changing it to percent form, we must multiply it by 100 and add the symbol "%". Therefore, we have 18.021978021 %.
Finally, rounding the value to the nearest whole number, we obtained 18.00% or just 18%.

Answer:
c = 16d + 18
Step-by-step explanation:
Answer:
The money was invested for 8 years.
Step-by-step explanation:
Given that a principal of $ 20,000 is invested at 6.25% and earns $ 10,000 simple interest, to determine how many years has the money been invested, the following calculation has to be performed:
(20,000 x 0.0625) x X = 10,000
1,250X = 10,000
X = 10,000 / 1,250
X = 8
Thus, the money was invested for 8 years.
Answer:
144
Step-by-step explanation:
100% of 300 is 300
50% of 300 is 150
2% of 100 = 2 which means that 2% of 300 = 6
150+6 = 156
300-156 = 144
