Elyse spent
25 of her money on 4 rulers and 7 glues. The cost of one glue was four times the cost of one ruler. She bought some more glues with
14 of her remaining money. How many glues did Elyse buy altogether?
4 rulers and
7 glues |
Remaining amount |
| 2x4 |
3x4 |
| |
More glues |
Left |
| |
1x3 |
3x3 |
| 8 p |
3 p |
9 p |
Cost of 1 ruler = 1 u
Cost of 1 glue = 4 u
Cost of 4 rulers = 4 x 1 u = 4 u
Cost of 7 glues = 7 x 4 u = 28 u
Total cost of 4 rulers and 7 glues
= 4 u + 28 u
= 32 u
8 p = 32 u
1 p = 32 ÷ 8 = 4 u
Amount that Elyse used to buy more glues
= 3 p
= 3 x 4 u
= 12 u
Number of more glues that Elyse bought
= 12 u ÷ 4 u
= 3
Total number of glues that Elyse bought
= 7 + 3
= 10
Answer(s): 10
