Natalie spent
25 of her money on 2 markers and 10 highlighters. The cost of one highlighter was thrice the cost of one marker. She bought some more highlighters with
14 of her remaining money. How many highlighters did Natalie buy altogether?

1x3 |
3x3 |
| 8 p |
3 p |
9 p |
Cost of 1 marker = 1 u
Cost of 1 highlighter = 3 u
Cost of 2 markers = 2 x 1 u = 2 u
Cost of 10 highlighters = 10 x 3 u = 30 u
Total cost of 2 markers and 10 highlighters
= 2 u + 30 u
= 32 u
8 p = 32 u
1 p = 32 ÷ 8 = 4 u
Amount that Natalie used to buy more highlighters
= 3 p
= 3 x 4 u
= 12 u
Number of more highlighters that Natalie bought
= 12 u ÷ 3 u
= 4
Total number of highlighters that Natalie bought
= 10 + 4
= 14
Answer(s): 14
