I found the same question on the internet and their answer is $9.76, which is obviously not in your choices. They deducted both given interest rates before multiplying it to the emergency fund amount and dividing it by 12 months.
4.57%−3.5%
=1.07%
(0.0107×10,943.89)÷12
=9.76
Another possible answer is $22.96 using 30 days / 365 days in a year.
Savings: 10,943.89 x (1/4) x 3.5% x (30/365) = $7.87
CD: 10,943.89 x the remainder (3/4) x 4.57% x (30/365) = $30.83
The difference between the two values: 30.83 - 7.87 = $ 22.96: so the first choice (I'm not so sure though)
H is equal to 9.
Here is an inside tip. Use the Desmos Graphing Calculator. It is very easy to use.
Answer: slope is 5/4 and y intercept is -7
Y=mx(slope)+b(y-intercept)
12 dogs to 92 cats.
12/92
Both 12 and 92 are divisible by 4.
12/4=3
92/4=23
Simplified ratio: 3/23
There are 3 dogs for every 23 cats.
