**Answer:**

a. Z: 30,000; T: 50,000

b. Z: 37.5%; T: 62.5%

**Step-by-step explanation:**

a. The "ratio units" add up to 3+5 = 8, so we can find the investment amounts by multiplying the ratio by 10,000

Z : T = 3 : 5 = 30,000 : 50,000

**Zoe invested 30,000****Toria invested 50,000**

__

b. Zoe's investment amount is 3/8 of the total, or ...

3/8 × 100% = 37.5%

Toria's percentage is the rest of it:

100% -37.5% = 62.5%

** Zoe invested 37.5% of the total; Toria invested 62.5% of the total**.
