Atiling company completes two jobs. the first job has $1200 in labor expenses for 40 hours worked, while the second job has $1560 in labor expenses for 52 hours worked. the relationship between the labor expenses and the hours worked is linear. which equation can be used to calculate the y-intercept of the linear equation?
1200 = 40(40) + b
1560 = 30(40) + b
1560 = 30(52) + b
1200 = 52(30) + b

The correct equation is 1560 = 30(52) + b

C is correct

Step-by-step explanation:

A tiling company completes two jobs.

The first job has $1200 in labor expenses for 40 hours worked.

Point: (40,1200)

The second job has $1560 in labor expenses for 52 hours worked.

Point: (52,1560)

Using two point we make linear equation.

First we find the slope of line

Slope intercept form: y=mx+b

where, b is y-intercept

y=30x+b

Passing points: (52,1560)   and   (40,1200)

Possible equation to find y-intercept

1200 = 30(40) + b

1560 = 30(52) + b

Hence, The correct equation is 1560 = 30(52) + b

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

hope this is what you were asking for!
