Answer 1

Answer:

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

$\frac{1}{4}$x - 10 = 70

$\frac{1}{4}$x = 70 + 10

x = 80 × 4

x = 320

An old wetie chocolate bar has 320 calories.

Answer 2

Answer:

An Old Westie chocolate bar contains 240 calories.

Step-by-step explanation:

If a medium sized apple has 70 calories and this is 10 calories less than 1/4 of an Old Westie chocolate bar, we must first find the difference between 70 and 10.

70 - 10 = 60

60 calories then is 1/4 of that of the chocolate bar, or, the chocolate bar is 4 times that of 60 calories

60 * 4 = 240

An Old Westie chocolate bar contains 240 calories.
