Let r = red pens
b =5r
g = 3r
The total number of pens
r+b+g

18 is a multiple of 9
1. 175m^2
2. 289.7cm^2
3. 42.8in^2
4. 62.4in^2
5. 88ft^2
6. 308.8cm^2
For all of these problems, I used the formula:
SA = Area of the base + 1/2(Perimeter of the Base)(Slant Height)

Answer:
Cash = 240, Credit = 330, Gift = 30
Step-by-step explanation:
We know from this the precentage of people using different payment methods
Cash = 40/100 = 40%
Credit card = 55/100 = 55%
Gift card = 5%
We can then find the number of people using each method regardless of total amount of people
Cash = 40% * 600 = 240
Credit = 55% * 600 = 330
Gift card = 5% * 600 = 30
Total = 240 + 30 + 330= 600
