$59.15
42.25 x .4 = 16.90
42.25 + 16.90 = 59.15
Answer: Hence, this investment would be worth of $366.756
Step-by-step explanation:
Since we have given that
Amount he invests = $350
Rate of interest compounded quarterly = 1.5%
Number of years = 50 years = 1.25 quarters
As we know the formula for "Compound Interest ":

For remaining half year, we first find the interest with using the above amount as principal amount.

Hence, this investment would be worth of

Answer:
Step-by-step explanation:
3(9x - 14/3x + 4 - 1 ≥ 2)
27x - 14x + 12 - 3 ≥ 6
13x + 9 ≥ 6
13x ≥ -3
x ≥ -3/13
Without calculating we can say that the system with the original cost $60 ( the cheaper system ) had a greater percent decrease.
This is because $10 is a greater percentage of $60 than it is of $90 ( if we calculate it is 16.66% in the first case and 11.11% in the second case).
