Q1) Mrs Tan bought some cups and pots in a shopping trip. The price of each cup was $3.20 while the price of each pot was $12.40. For every 4 pots bought, she was given one such cup for free. After receiving the free cups, the number of cups was 1/3 of the number of pots bought. If Mrs Tan paid a total of $2280,
(a) how much pots did she buy?
(b) how much more did she pay for the pots than the cups?
1 cup ------- $3.20
1 pot ------- $12.40
4 pots, 1 cup free
cups : pots
1 : 3
4 : 12
12 pots ------- 12 x $12.40 = $148.80
every 4 cups - 3 cups free = 1 cup bought
1 cup ------- $3.20
$3.20 + $148.80 = $152
$2280/$152 = 15 (sets)
15 x 12 = 180 (pots)
(b)
15 x $3.20 = $48
180 x $12.40 = $2232
$2232 - $48 = $2184
Ans : (a)180 pots; (b)$2184 more.
cups : pots
1 : 3
4 : 12
Why do you need to multiply it by four? Can anyone help me to explain this? Thank you.[/quote]
