V125BC [204]

Answer:

$18.36

Step-by-step explanation:

In this question, we have to find the cost of the cake for the customer who orders a month early.

We know that the original price of the cake is $30.

We also know that there was a 28% discount and a 15% discount added to the purchase.

Remember, You don't add discount percentages together, you discount the prices separately.

Solve:

First, apply the 28% discount.

30 · 0.28 = 8.40

30 - 8.40 = 21.60

Now apply the 15% discount to the new price.

21.60 · 0.15 = 3.24

21.60 - 3.24 = $18.36

They needed to pay $18.36 for the cake.

Step-by-step explanation:

Part A - Where did Phillip make a mistake? Justify your answer using complete sentences.

Use order of operation (PEMDAS)

He should multiply 8 x 4 first

Part B - Solve the expression correctly in the space below.

(5 x 9) - 8 x 4

= 45 - 32

= 13

Part C - Use the same rules of order of operations to solve the expression (8-4) +9 x 3. Explain your steps as you solve it.

(8-4) + 9 x 3

Step 1:   4 + 9 x 3  (Subtract in the parenthesis first)

Step 2:   4 + 27   (Multiply 9 x 3)

Step 3:   31         (Add)

New York City is a popular feild trip destination. This year the senior
lilavasa [31]

Step-by-step explanation: look so if you have

shcool A its 8v+4b=12

and

School B: 12v+4b= 16

since both classes used 4 busses we can use elimination by subtracting the A class Equation from the b class equation to solve from v for its value Then, use either equation and the now found value for v to solve for b.

You should find part of the process to be

12v+4b-(8v+4b)=12-16 which shows the van holds only a few people even before continuing the solution.
