The sum is 15.
Divide 15 by three to get Jane's age= 5
The remainder, which is J * 2, or ten, is Randy's age.
Randy is ten.
Step-by-step explanation:
17=500*2*x
17=1000x
17/1000=0.017
rate is 1.7 percent
Step-by-step explanation:
It doubles in value every 30 years, which means it increases by 100%.
A = 60,000 (1 + 1)^(t/30)
A = 60,000 (2)^(t/30)
In 2035 (55 years later), the value is:
A ≈ 214,000
Answer:
6.25 years
(6 years 3 months)
Step-by-step explanation:
<u />
<u>Simple interest formula</u>
A = P(1 + rt)
where:
- A = final amount
- P = principal
- r = interest rate (in decimal form)
- t = time (in years)
Given:
- A = $1,500
- P = $1,000
- r = 8% = 0.08
Substitute given values into the formula and solve for t:
⇒ 1500 = 1000(1 + 0.08t)
⇒ 1500 = 1000 + 80t
⇒ 500 = 80t
⇒ t = 6.25 years
