Question

1. “Zoe and Toria are going into business. They need 80,000 to start the business. Their investment is 3:5, respectively.

a. What's Zoe & Ares individual investment amounts?

b. What percent did each person invest?

Answer 1

9514 1404 393

Answer:

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

b. Z: 37.5%; T: 62.5%

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.
