Box of 3 spoons, original = $9
Box of 3 spoons, discounted price = (100% – 10%) x $9 = $8.10
Packet of 4 forks, original = $12
Packet of 4 forks, discounted price = (100% – 20%) x $12 = $9.60
LCM of 3 and 4 —> 12
1 set, original = 12 spoons and 12 forks (24 cutlery items) = (12 ÷ 3) x $9 + (12 ÷ 4) x $12 = $72
1 set, discounted price = 12 spoons and 12 forks (24 cutlery items) = (12 ÷ 3) x $8.10 + (12 ÷ 4) x $9.60 = $61.20
Diff in both sets (saved) = $72 – $61.20 = $10.80
No. of sets = $43.20 ÷ $10.80 = 4
Total forks Sally bought = 4 x 4 = 16 (a)
Total paid, discounted price = 4 x $61.20 = $244.80 (b)
Hope you understand and all the best for your exams! :))
May i know if the answer for a) should be 4*12 forks =48
