Irene bought an equal number of cranberry croissants and apricot croissants. She paid $10.50 more for the apricot croissants and the cranberry croissants.
- How many croissants did she buy?
- How much did she spend altogether?
(a)
Irene bought an equal number of cranberry croissants and apricot croissants. Make the number of cranberry croissants and apricot croissants the same. LCM of 6 and 4 is 12.
Number of sets of 6 in 12
= 12 ÷ 6
= 2
Cost of 1 set of 12 cranberry croissants
= 2 x 2.40
= $4.80
Number of sets of 4 in 12
= 12 ÷ 4
= 3
Cost of 1 set of 12 apricot croissants
= 3 x 2.30
= $6.90
Amount that Irene paid more for 1 set of 12 apricot croissants than 1 set of 12 cranberry croissants
= 6.90 - 4.80
= $2.10
Number of sets of $2.10
= 10.50 ÷ 2.10
= 5
Total number of croissants in 1 set of 12 apricot croissants and 12 cranberry croissants
= 2 x 12
= 24
Number of croissants that Irene bought
= 5 x 24
= 120
(b)
Cost of croissants in 1 set of 12 apricot croissants and 12 cranberry croissants
= 4.80 + 6.90
= $11.70
Total amount that Irene spent altogether
= 5 x 11.70
= $58.50
Answer(s): (a) 120 ; (b) $58.50
