Answer:

Jon will have more money than Sara after 1 year . Jon will have 1440.738 dollars excess money than Sara

Step-by-step explanation:

As we know

Amount received after application of compound interest is calculated as

$A = P (1+\frac{r}{n})^{nt}$

For Jon

$A = 4500(1+\frac{7}{4*100})^{4} \\A= 4823.366$

Jon receives $ 4823.366 after one year

For Sara

$A = 3250 (1+\frac{4}{365*100})^{365*1} \\A = 3382.628$

Jon will have more money than Sara after 1 year . Jon will have 1440.738 dollars excess money than Sara

Ryan and Sarah collect baseball cards. Ryan has 150 baseball cards and collects 10 cards per week. Sarah has 233 baseball cards

ICE Princess25 [194]

Answer:

About 17 weeks

Step-by-step explanation:

Given

Ryan:

$Initial = 150$

$Additional = 10$ (weekly)

Sarah:

$Initial = 233$

$Additional = 5$ (weekly)

Required

Determine the number of weeks they have the same cards

Represent the number of weeks with w:

For Both individuals, number of card at any given week is:

$Initial + Additional * w$

So,

For Ryan, the expression is:

$150 + 10 * w$

$150 + 10w$

For Sarah, the expression is:

$233 + 5 * w$

$233 + 5 w$

To determine the number of weeks, we have to equate both equations:

$150 + 10w= 233 + 5 w$

Collect Like Terms

$10w - 5w = 233 - 150$

$5w = 83$

Solve for w

$w = 83/5$

$w = 16.6$

16.6 implies about 17 weeks, because 16.6 approximates to 17

Conclusively, Ryan and Sarah will have the same number of balls in about 17 weeks
