Given that the medium sized apple has 70 calories this 10 calories less than one-fourth of the calories in the old Westie chocolate bar, considering the later part of the sentence,

10 calories less than one-fourth of the calories in the old Westie chocolate bar can be expressed mathematically as

(1/4)x - 10 where x is the calories in the old Westie chocolate bar. As such, it means that

(1/4)x - 10 = 70

1/4)x = 80

x = 80 * 4

= 320 calories
