Answer 1

(a) 280

(b) £26

Explanation:

(a) 20 workers eat 2 biscuits a day.

20 × 2 = 40

Since there are 7 days a week, multiply the 40 x 7 to find how many biscuits are eaten each week.

40 × 7 = 280

280 biscuits are eaten every week.

(b) Now, divide 280 (the number of biscuits eaten each week) by 14 (the number of biscuits in a packet) to find how many packets are eaten weekly.

280 ÷ 14 = 20

Now you have the number of packets eaten each week, so you can determine the price spent on biscuits. Multiply 20 packets by the price per packet, which is £1.30.

20 × 1.30 = 26

The office spends £26 on biscuits each week.
