The table shows the prices of scones at two shops. The scones are only sold in sets of 5 scones in Emma's Bakery or sets of 6 scones in Anna's Bakery.

Shop	Price of scones
Emma's Bakery	5 for $14
Anna's Bakery	6 for $16

1. Dana has $48.90. She wants to buy 30 scones from Anna's Bakery. How much more money does she need to buy the 30 scones?
2. Michael has $63. He wants to buy the greatest possible number of scones with his money from one of the two shops. What is the greatest possible number of scones he can buy with his money?

(a)
Number of sets of 6 scones
= 30 ÷ 6
= 5

Cost of 30 scones 
= 5 x 16
= $80

Amount that Dana needs more to buy the 30 scones
= 80 - 48.90
= $31.10

(b)
Number of sets of 5 scones that Michael could buy at Emma's Bakery
= 63 ÷ 14
= 4 r 7

Number of scones that Michael could buy at Emma's Bakery
= 4 x 5
= 20 (More)

Number of sets of 6 scones that Michael could buy at Anna's Bakery
= 63 ÷ 16
= 3 r 15

Number of scones that Michael could buy at Anna's Bakery
= 3 x 6
= 18

Greatest possible number of scones that Michael can buy with his money = 20

Answer(s): (a) $31.10; (b) 20
