Cindy spent
35 of her money on 4 correction tapes and 5 rulers. The cost of one ruler was four times the cost of one correction tape. She bought some more rulers with
14 of her remaining money. How many rulers did Cindy buy altogether?

1 p |
3 p |
Cost of 1 correction tape = 1 u
Cost of 1 ruler = 4 u
Cost of 4 correction tapes = 4 x 1 u = 4 u
Cost of 5 rulers = 5 x 4 u = 20 u
Total cost of 4 correction tapes and 5 rulers
= 4 u + 20 u
= 24 u
6 p = 24 u
1 p = 24 ÷ 6 = 4 u
Amount that Cindy used to buy more rulers
= 1 p
= 1 x 4 u
= 4 u
Number of more rulers that Cindy bought
= 4 u ÷ 4 u
= 1
Total number of rulers that Cindy bought
= 5 + 1
= 6
Answer(s): 6
