Olivia spent
35 of her money on 8 correction tapes and 7 glues. The cost of one glue was four times the cost of one correction tape. She bought some more glues with
16 of her remaining money. How many glues did Olivia buy altogether?

1 p |
5 p |
Cost of 1 correction tape = 1 u
Cost of 1 glue = 4 u
Cost of 8 correction tapes = 8 x 1 u = 8 u
Cost of 7 glues = 7 x 4 u = 28 u
Total cost of 8 correction tapes and 7 glues
= 8 u + 28 u
= 36 u
9 p = 36 u
1 p = 36 ÷ 9 = 4 u
Amount that Olivia used to buy more glues
= 1 p
= 1 x 4 u
= 4 u
Number of more glues that Olivia bought
= 4 u ÷ 4 u
= 1
Total number of glues that Olivia bought
= 7 + 1
= 8
Answer(s): 8
