Find the percent increase round to the nearest percent from 13 friends to 15 friends percent increase is what percent

15%

Step-by-step explanation:

Since it is increasing from 13 to 15, the difference is 2

so you now

have to divide 2 by 13

because 13 is the original friend amount.

2 divided by 13 is equal to 0.153846153846153846153846153846

since the units are percent

it should techincally turn into

15.3846153846153846153846153846

but since you are rounding to the nearest percent

it would be 15%

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
