Answer:
The annual rate of interest is 2.56%
Step-by-step explanation:
Given as :
Principal Amount investing every week = $25
Principal Amount investing in 5 years = $25 × 5 × 52 = p = $6500
The Amount adds after 5 years = A = $7380
Time period = t = 5 years
Let annual rate of interest = r %
<u>Now, According to question</u>
Amount after 5 years = Principal ×
Or, A = p ×
Or, $7380 = $6500 ×
Or, =
Or, 1.135 =
Or, = 1 +
Or, 1.0256 = 1 +
Or, 1.0256 - 1 =
Or, 0.0256 =
∴ r = 0.0256 × 100
i.e r = 2.56
So, The rate of interest = r = 2.56
Hence, The annual rate of interest is 2.56% Answer

Answer:
x = 3
Step-by-step explanation:
First, multiply all four terms by 10 to eliminate the fractions:
4x - 8(x-4) = 13x - 19
Next, carry out the indicated multiplication, obtaining:
4x - 8x + 32 = 13x - 19
Combining the x terms, we get:
-4x + 32 = 13x - 19, or
32 = 17x - 19
Combining the constants, we get 51 = 17x, and so x = 51/17 = 3.
