Answer:
27 years approx
Step-by-step explanation:
Given data
Principal P= $ 3,000
Final amount A= $ 7000
Rate r= 5%
The simple interest expression is
A=P(1+rt)
substitute and solve for t
7000=3000(1+0.05t)
7000=3000+150r
7000-3000=150r
4000=150t
t= 4000/150
t= 26.66
Hence, the time is 27 years approx
Answer:
50=2(10+w)
Step-by-step explanation:
We know that perimeter is equal to the sides of a shape
A rectangle has two of the same length and two of the same width
P=2l+2w
We know the perimeter and length so plug that in and solve for w
50=2(10)+2w
50=2(10+w) - That matches answer choice D
30=2w
w=15
