a. The maximum number of students were absent on Friday (150 students) and the minimum number of students were absent on Saturday (80 students).

b. On Wednesday and Friday 135 + 150 = 285 students were absent.

Q7

Total number of students = 400

Bus: $\frac{200}{400}\cdot 100\% = 50\%$

Bicycle: $\frac{100}{400}\cdot 100\% = 25\%$

On foot: $\frac{80}{400}\cdot 100\% = 20\%$

By car: $\frac{20}{400}\cdot 100\% = 5\%$
