The simple interest on the balance of $3,500 is 8.88%
The simple interest on the balance of $7,500 is 7.48%
What is simple interest?
The simple interest on a credit card is the annual interest multiplied by the credit card balance, in other words, the total interest paid on both credit cards in the year under review summed up to $797.
Let us assume that simple interest on the credit card with a balance of $7500 is X
interest=$7500*X
The interest on the other credit card would be X+1.4%
interest in dollars=$3500*(X+1.4%)
total interest cost in dollars on both cards can be determined as the sum of the interest costs
total interest=$7500*X+$3500*(X+1.4%)
total interest=7500X+3500X+49
total interest=797
797=7500X+3500X+49
797=10000X+49
797-49=10000X
748=10000X
X=748/10000
X=7.48%
The simple interest on the credit balance of $7500 is 7.48%
The simple interest on the credit balance of $3,500=7.48%+1.4%
The simple interest on the credit balance of $3,500=8.88%

Option B) Determine the volume of the cake V= πr²h and divide that amount by 18
<u>Step-by-step explanation:</u>
- It is given that, the birthday cake is in the shape of the cylinder.
- Therefore, to find the entire volume of the cake, the volume of the cylinder formula is used.
<u>The volume of the cylinder is given by,</u>
Volume of the birthday cake = πr²h
After that, it was asked to find the volume of each piece of the cake.
In this case, the birthday cake is cut into 18 pieces.
We already know the total volume of the birthday cake which is πr²h.
In order to find the volume of each piece of cut cake, the total volume must be divided by the number of parts it has been cut into pieces.
Here, the whole part of the cake is 1.
The number of parts it has been divided after it is made into pieces = 18 parts.
Therefore, the volume of the birthday cake must be divided by 18 to get the volume of each piece of cake.
Option B) Determine the volume of the cake V= πr²h and divide that amount by 18 is correct.
