Question

after spending 80% of her daily allowance, Ola found out she had 25k left. How much was her total allowance?

Answer 1

31.25 k

Explanation:

80 % * x = 25 k

.80 x = 25 k

x = 25 k / .80 = 31.25 k

Answer 2

125k

Explanation:

You want to know Ola's daily allowance if 25k remained after 80% was spent.

Setup

The fraction remaining was 100% -80% = 20%. If that fraction of Ola's allowance (a) is 25k, we have ...

0.20a = 25k

Solution

Dividing by 0.20, the value of 'a' is shown to be ...

a = 25k/0.20 = 125k

Ola's total daily allowance was 125k.
