Answer:

Question 3: 93 Question 4: -18

Step-by-step explanation:

Use Order of Operations (BEDMAS - Brackets Exponents Division Multiplication Addition and Subtraction).

Question 3:

Start with the numbers inside the brackets.

3^2 (4+6) + 3

= 3^2 (10) + 3

Then, solve the exponents.

= 9 (10) + 3

Multiply 9 and 10.

= 90 + 3

Add the numbers.

= 93

Question 4:

Again, start with the brackets.

3 (4+2) - 6^2

= 3 (6) - 6^2

Then, solve the exponent.

= 3 (6) - 36

Multiply 3 and 6.

= 18 - 36

Subtract the numbers.

= -18 (You can do 36 - 18 which is 18, then add the negative sign)

Since Marnie has bought her car,the value has gone down 15%.If her car is 13000 right now,how much was it worth when she bought

Serggg [28]

Percentage of depreciation of the car that Marie bought = 15%
Present value of the car = 13000
Let us assume that the value of the car at the time of buying = x
So
The percentage valuation of the car now = (100 - 15) percent
= 85 percent
Then
(85/100) * x = 13000
85x = 13000 * 100
85x = 1300000
x = 1300000/85
= 15294.12
So the actual cost of the car is 15294.12. I hope the procedure is clear enough for you to understand.
