Answer:
c. 9t+45 that shows distributive property
where it shows a*(b+c)=(a*b)+(b*c).so,9(t+5)=9*t+9*5
Answer:
APR = 416%
EAR = 5370.60%
Step-by-step explanation:
Given:
Interest rate = 7.8% per week
Now,
In an year there are total 52 weeks
thus,
The APR (Annual percentage rate) = Interest rate × Total weeks in an year
or
APR = 8% × 52
or
APR = 416%
and, EAR ( Effective Annual Rate ) = ( 1 + r )ⁿ - 1
Here,
r is the interest rate per week
n is the total weeks in an year
thus,
EAR ( Effective Annual Rate ) = ( 1 + 8% )⁵² - 1
= ( 1 + 0.08 )⁵² - 1
= 53.7060
or
53.7060 × 100% = 5370.60%
I believe is A, the first one
Answer:
r=5%
New balance=$ 517.5
Step-by-step explanation:
We use the simple interest formula:
I=prt.
to determine the rate per annum of a principal of $450 that is invested for 3 years and earned an interest of $ 67.5
We substitute to get:
67.5=450×r×3
We simplify to get:
The rate of interest is 5%
The new balance is
Principal + Interest.
The new balance $517.5
