Trevon and Ming are selling cheesecakes for a school fundraiser. Customers can buy French silk cheesecake and apple cheesecake.
qwelly [4]

The cost of one French silk cheesecake is $5 and one apple cheesecake is $14.

Step-by-step explanation:

Let,

Cost of one French silk cheesecake = x

Cost of one apple cheesecake = y

According to given statement;

8x+y=54     Eqn 1

3x+y=29     Eqn 2

Subtracting Eqn 2 from Eqn 1

(8x+y)-(3x+y)=54-29\\8x+y-3x-y=25\\5x=25

Dividing both sides by 5

\frac{5x}{5}=\frac{25}{5}\\x=5

Putting x=5 in Eqn 1

8(5)+y=54\\40+y=54\\y=54-40\\y=14

The cost of one French silk cheesecake is $5 and one apple cheesecake is $14.

Principal = $2,400<br> Rate = 4%<br> Time = 30 months
grandymaker [24]

Answer:

$240

Step-by-step explanation:

I = prt

I = (2,400) (0.04) (2.5)  

note: I changed 4% to a decimal and 30 months to 2.5 years

I = 96 (2.5)

I = 240   <-- The interest

------------------------------------------------------------------------------------------------------------

The simple interest accumulated on a principal of $ 2,400.00  at a rate of 4% per year for 2.5 years (30 months) is $240.00.

---------------------------------------------------------------------------------------------------------

* Last time I did interest was in 6th grade and I don't remember much. So I am very sorry if my answer is wrong *
