Answer:
Joel had 120 dimes and 80 quarters.
Step-by-step explanation:
Given that Joel had 200 coins, which were dimes and quarters, and the total value was $ 32, to determine how many coins of each type he had, the following calculation must be performed:
0.25 - 0.10 = 0.15
200 x 0.10 = 20
32 - 20 = 12
12 / 0.15 = 80
200 - 80 = 120
(80 x 0.25) + (120 x 0.1) = X
20 + 12 = X
32 = X
Thus, Joel had 120 dimes and 80 quarters.
Answer:
$10408.08>$10400
She will earn more using the daily compounding method.
Step-by-step explanation:
Investment 1 cost $10,000 and earns 4% interest each year.
If interest was paid once a year
Amount = P(1+r)ⁿ
= 10000(1+0.04)
=10000(1.04)
=$10400
If the interest was compounded daily
Amount = P(1+r/n)ⁿᵗ
=10000(1+0.04/365)³⁶⁵
=$10408.08
Since $10408.08>$10400, it means Odette will earn more using the daily method for one year.
