It takes 830 bricks to construct a wall that measures 14 feet 9 inches long and 6 feet high. the crew you hire can lay 300 bricks/hour. the cost of the labor is $4,000 per eight-hour workday and you can pay for a partial day. you need to build a wall 36' 6" long and 6' high. how much will the new wall cost? a.) $3,400.20 b.) $1,383.53 c.) $3,423.35 d.) $10,256.51 hint: you will need to convert the daily rate into an hourly rate by dividing by 8. you will also need to determine a brick-per-square-foot rate.

B.) $1,383.53

Step-by-step explanation:

Given: The total number bricks required to make the wall= 830

The speed of crew= 300 bricks/hour

Total hours they take to make the wall=

The cost of labour =$4,000 per eight-hour

⇒The cost of labour for 1 hour =

Now, the cost of wall=

Hence, B is the right answer, the cost of the new wall= $1383.53

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
