Answer:
<u>I will take around 1 year and 8 months to earn $ 45 of interest on this investment</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Interest earned = $ 45
Investment = $ 790
Annual simple interest rate = 3.4% = 0.034
2. How much time would it take to earn $45?
Let's recall the formula for calculating the simple interest of an investment:
A = P * (1 + rt)
Replacing with the values we already have:
835 = 790 + (1 + 0.034t).
Where t is the time we want to calculate
835 = 790 + 26.86t
26.86t = 835 - 790
26.86t = 45
t = 1.68 (Rounding to the next hundredth)
<u>t ≅ 1 year and 8 months</u>

Answer:x = 12
Step-by-step explanation:
The equation One-half x + 3 = two-thirds x + 1 is expressed as
x/2 + 3 = 2x/3 + 1
The first step would be to to find the lowest common multiple of the left hand side of the equation and the right hand side of the equation and multiply the left hand side of the equation and the right hand side of the equation by the lowest common multiple. The lowest common multiple is 6. Therefore,
x/2 × 6 + 3 × 6 = 2x/3 × 6 + 1 × 6
3x + 18 = 4x + 6
4x + 6 = 3x + 18
Subtracting 3x and 6 from the left hand side of the equation and the right hand side of the equation, it becomes
4x - 3x + 6 - 6 = 3x - 3x + 18 - 6
x = 12
