percentage increase of the amount in her account:
(a) during the first year.
(b) during the second year.
(c) over the two years.
Give your ansivers correct to 2 decimal places

(a) 5.00%

(b) 7.00%

(c) 12.35%

Step-by-step explanation:

(a) Find the difference, in £, between the value after the first year and the original value. Divide that by the original value and multiply by 100:

(b) Find the difference, in £, between the value after the second year and the value after the first year. Divide that by the value after the first year and multiply by 100:

(c) Find the difference, in £, between the value after the second year and the original value. Divide that by the original and multiply by 100:

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
