John who is 20 years old is 8 years older than 2 times the age of carlos. how old is carlos

Carlos is 6

let x be Carlo's age then

2x + 8 = 20 → (solve for x)

subtract 8 from both sides

2x = 20 - 8 = 12

divide both sides by 2

x = = 6

Carlos is 6 years old

c = Carlos

j = John

2c + 8 = j

2c + 8 = 20

2c = 20 - 8

2c = 12

c = 12 : 2

c = 6

6*2+8=20

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
