Zara and Jade had an equal number of chocolate bars. After Zara bought another 24 chocolate bars and Jade bought another 4 chocolate bars, Zara had thrice as many chocolate bars as Jade. Find the number of chocolate bars that each of them had at first.
| |
Zara |
Jade |
| Before |
3 u - 24 |
1 u - 4 |
| Change |
+ 24 |
+ 4 |
| After |
3 u |
1 u |
The number of chocolate bars that Zara and Jade had at first is the same.
3 u - 24 = 1 u - 4
3 u - 1 u = 24 - 4
2 u = 20
1 u = 20 ÷ 2 = 10
Number of chocolate bars that each had at first
= 10 - 4
= 6
Answer(s): 6
