Answer:

5. 8

6. 18

Step-by-step explanation:

a(a^2 + a - 1) + 7 =

= a^3 + a^2 - a + 7

For a = -1,

= (-1)^3 + (-1)^2 - (-1) + 7

= -1 + 1 + 1 + 7

= 8

2ab(a + b) - 3ab(a - b) =

= 2a^2b + 2ab^2 - 3a^2b + 3ab^2

= -a^2b + 5ab^2

For a = 1 and b = 2,

= -(1)^2(2) + 5(1)(2)^2

= -1(2) + 5(4)

= - 2 + 20

= 18

The table shows the total cost for different numbers of jackets. Number of jackets 2 5 7 Total cost ($) 46. 50 116. 25 162. 75 W

Bond [772]

The cost price of 1 jacket is $23.25 and the cost price of 3 jackets is $69.75.

<h3>What is the cost price?</h3>

Cost price is the total amount of money to produce a given product or provide a given service.

Given cost prices for jackets are,

Jackets Cost Price

2 46.5

5 116. 25

7 162. 75

We need to calculate the cost price of 3 jackets. First, we need to find out the cost price of one jacket.

$2 \; \rm Jackets =\$ 46.50$

$1 \;\rm Jacket = \dfrac {\$46.50}{2}$

$1 \;\rm Jacket = \$ 23.25$

Now the cost price of 3 jackets is given as,

$3\;\rm Jackets = \$23.25 \times 3$

$3\;\rm Jackets = \$69.75$

Hence we can conclude that the cost price of 3 jackets is $69.75.
