Paula has $10 and earns $0.50 per lap she runs for her school’s fundraiser. Jackie has $15 and earns $0.25 per lap she runs for

algol13

Answer: After 20 laps Paula will have more money than Jackie.

Step-by-step explanation:

Let x = Number of laps.

Given, Paula has $10 and earns $0.50 per lap she runs for her school’s fundraiser.

i.e. Total amount Paula has =$ [ 10 +0.50 (Number of laps)]

= $ [10+0.50x]

Jackie has $15 and earns $0.25 per lap she runs for her school’s fundraiser.

i.e. Total amount Jackie has =$ [ 15 +0.25 (Number of laps)]

= $ [15+0.25x]

When Paula has more money , then

$15+0.25x< 10+0.50x\\\\\Rightarrow\ 15-10$

Hence, after 20 laps Paula will have more money than Jackie.

Dr. Clarence invested $5000 in an account that draws 3.2% interest, compounded annually. What is the total value of the account

castortr0y [4]

It's simple, you just have to times everything. 5000 x 3.2% x 5 years. After calculating these, 3.2 is as 0.032 so there would be three decimal places. So then it will e 5000 x 0.032 x 5
