Amedium sized apple has 70 calories . this is 10 calories less than 1/4 of the calories in an old westie choclate bar. we need to find out how many calories are in the choclate bar. choose the best model for the first step in this problem

320 calories.

Step-by-step explanation:

It is given that a medium sized apple has 70 calories .

This is 10 calories less than 1/4 of the calories in an old westie chocolate bar.

Let the calories in an westie chocolate bar = x

Now we establish an equation and find the value of  x

x - 10 = 70

x = 70 + 10

x = 80 × 4

x = 320

An old wetie chocolate bar has 320 calories.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
