Let’s tackle a practical problem about shopping with a limited budget! Packs of batteries cost £2.85 each, and Ben has £45 to spend. Ben wants to buy as many packs of batteries as he can. We need to figure out how much change he should receive.
Step 1: Calculate the Number of Packs Ben Can Buy
Ben has £45, and each pack costs £2.85. To find out how many packs he can buy, we divide his total money by the cost per pack:
£45 / £2.85/pack = 15.789… packs
Since Ben can only buy whole packs of batteries, we need to round down to the nearest whole number. He can buy 15 packs.
Step 2: Calculate the Total Cost of the Batteries
Ben buys 15 packs, and each pack costs £2.85. To find the total cost, we multiply the number of packs by the cost per pack:
15 packs * £2.85/pack = £42.75
Step 3: Calculate Ben’s Change
To find Ben’s change, we subtract the total cost of the batteries from the amount he started with:
£45 – £42.75 = £2.25
Answer:
Ben should get £2.25 change.
This problem involves division, multiplication, subtraction, and rounding. These are all core skills, and getting essential maths help to master them can make a big difference in everyday life.
