Answer:
Martina has 18,000
Step-by-step explanation:
- Set up the 4/5 the amount Tamara has as a proportion. 4/5 = x/20000
- Then cross multiply
- 4 * 20,000 = 80,000
- 80,000 = 5x
- Divide and get 16,000 (This is 4/5 of what Tamara has)
- Set up what Martina has as a proportion. 8/9 = 16,000/x
- Cross multiply 8x = 16,000 * 9
- 8x = 144,000
- Divide by 8
- 18,000 :)
