Answer:
there are 150 in a twinkie and 300 in a cupcake
Step-by-step explanation:
3 x 150 = 450 then 150 x 2 = 300
To answer this, we can use as 1 Twinkie as x, and a cupcake as y. First, we can make an equation. Since 3 Twinkie’s and 1 cupcake add up to 750 calories, we have: 3x+y=750. Since a cupcake has twice the amount of calories, then 2x=y. Next, we can substitute the y, and we get:
3x+2x=750
Combining like terms
5x=750
Divide by 5 on both sides
x = 150
Since a cupcake has twice the amount of calories than a Twinkie, then one Twinkie is 150*2=300.
3x+2x=750
Combining like terms
5x=750
Divide by 5 on both sides
x = 150
Since a cupcake has twice the amount of calories than a Twinkie, then one Twinkie is 150*2=300.
