Answer:
simplify
Step-by-step explanation:
11 + 12 = 33
12/33 x 100 = 36.4%
Teachers / Students = 3 / 74
Teachers / 2,500 = 3 / 74
To solve a proportion,
you cross-multiply: Teachers x 74 = 2,500 x 3
Divide each side by 74 : Teachers = 2,500 x 3 / 74
= 101.4 ===> 101 teachers
Answer:
4 years and 2 months
Step-by-step explanation:
<u>Simple interest formula</u>
A = P(1 + rt)
where:
- A = final amount
- P = principal amount
- r = interest rate (in decimal form)
- t = time (in years)
Given:
- A = $500 × 2 = $1,000
- P = $500
- r = 24% = 0.24
Substitute the given values into the formula and solve for t:







Therefore, it takes 4 years and 2 months for the initial investment of $500 to double at a simple interested rate of 24%.
