Answer:
Kevin is going to be able to have enough money for the concert the fastest
Philip needs at least 4 weeks
Kevin needs at least 3 weeks
Step-by-step explanation:
<u>Philip</u>
- $8.75/hour * 6 hours/weekend * 1 weekend/week = $52.5/week
Let's call x to the number of weeks Philip needs to reach $225.
52.5*x + 45 = 225
52.5*x = 225 - 45
x = 180/52.5
x = 3.43
He needs at least 4 weeks
<u>Kevin</u>
- 3 hours/day * $7.5/hour *3 days/week = $67.5/week
Let's call y to the number of weeks Kevin needs to reach $225.
67.5*y + 30 = 225
67.5*y = 225 - 30
y = 195/67.5
y = 2.9
He needs at least 3 weeks
The money can be withdrawn from the account every two months for the next 6 years is $20, 625, 000
<h3>What is compound interest?</h3>
The formula for compound interest is given as;
![A = P ( 1 + \frac{r}{n} )^n^t](https://tex.z-dn.net/?f=A%20%3D%20P%20%28%201%20%2B%20%5Cfrac%7Br%7D%7Bn%7D%20%29%5En%5Et)
P = principal interest = $25, 000
r = rate = 4. 5%
n = 2 months
t = 6 years
A = ![25, 000 ( 1 + \frac{4. 5}{2} )^2 ^*^6](https://tex.z-dn.net/?f=25%2C%20000%20%28%201%20%2B%20%5Cfrac%7B4.%205%7D%7B2%7D%20%29%5E2%20%5E%2A%5E6)
A = ![25, 000(1 + 0. 75)^1^2](https://tex.z-dn.net/?f=25%2C%20000%281%20%2B%200.%2075%29%5E1%5E2)
A = ![25, 000( 825. 00)](https://tex.z-dn.net/?f=25%2C%20000%28%20825.%2000%29)
A = $20, 625, 000
Thus, the money can be withdrawn from the account every two months for the next 6 years is $20, 625, 000

These types of pieces forces us to think about them, however, it does not matter how it’s the most important, what matters is how it makes you, yourself feel, this kind of abstract art is strictly real and gives us space to think on our own, patterns and unity in work , homogeneity and uniqueness are the most factors that defines the good paint or failure on.
5/6= c/9
Cross mutiple. 5* 9= 45 . c*6
45= 6c
divide by 6 for 45 and 6c
45/6= 6c/6
45/6= c
Reduce 45/6. Divide by 3
45/3, 6/3
15/2= c
Answer: c= 15/2 or in decimal form , c= 7.5
