Lin needs to save up $20 for a new game. How much money does she have if she has saved the following percentages of her goal. Explain your reasoning. 25% 75% 125%

25% of 20$ is 5$

75% of 20$ is 15$

125% of 20$ is 25$

She has $80 if she saved 25% for her goal

She has $26.66 if she saved 75% for her goal

She has $16 if she saved 125% for her goal

Step-by-step explanation:

1. If she has $20 on saving 25% of a particular amount of money

Let represent the amount with y,

Therefore

25% of y = $20

25/100 * y = 20

25y/100 = 20

25y = 100x20

25y = 2000

y = 2000/25

y = $80

2. If she has $20 on saving 75% of a particular amount of money

Let represent the amount with y,

Therefore

75% of y = $20

75/100 * y = 20

75y/100 = 20

75y = 100x20

75y = 2000

y = 2000/75

y = $26.66

3. If she has $20 on saving 125% of a particular amount of money

Let represent the amount with y,

Therefore

125% of y = $20

125/100 * y = 20

125y/100 = 20

125y = 100x20

125y = 2000

y = 2000/125

y = $16
