Jessica has 2 plates of cookies. The first plate has twice as many as the second plate. The second plate has 8 cookies. How many cookies does jessica have altogether

Jessica has 24 cookies

Step-by-step explanation:

let the amount of cookies in the first plate be "x" and the ones in the second plate be y

y=2x

if x is 8, y = 16

So therefore, the total amount of cookies = x + y

which is 8+16, which is equal to 24
