Hi AC, i cannot understand the working. Can assist in explaining more in steps and deriving the figures as my kid also has same question
Hi, there is mistake on a) calculation.
Answer should be 98
U = 77, I accidentally put 177
¾×77 + 57/4 + 26 = 98
b) % increased =（98-77)/77 × 100% = 27.2727273%
= 27.3%
