Four machines, each costing $5,700, were purchased for an office. Each machine requires

liubo4ka [24]

The number of months it would take to recover the cost of the machines is 12 months.

<h3> What is the total cost of the machines and the salary of the operators? </h3>

Total cost of the four machines = $5700 x 4 = $22,800

The total salaries of the machine operators in t months = 4t x $1,00 = $4,400t

Total cost = $22,800 + $4,400t

<h3>What is the amount saved by replacing the 8 clerks in t months? </h3>

($750 x 2t) + ($650 x 3t) + ($950 x 3t)

= $1500t + $1,950t +$2,850t

= $6300t

<h3>In how many months would it take to recover the cost of the machines? </h3>

$22,800 + $4,400t = $6300t

Combine similar terms

$22,800 = $6300t - $4400t

$22,800 = $1900t

Divide both sides by 1900

t = 12 months

Kittens weigh about 100 grams when born and gain 7 to 15 grams per day. If a kitten weighed 100 grams at birth and gained 8 gram

tangare [24]

25 days

First, start with an equation

100+8x= kittens weight

(X representing the days)

Since you’re trying to figure out the number of days it takes the kitten to triple it’s weigh you multiply it’s initial weight by 3 (100•3)

Then, you output 300 into the equation and solve

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 40 pounds each, and the small boxes

denis23 [38]

Large box 70, small 55
x+y=125
40x+20y=3900
y=125-x
40x+20(125-x)=3900
40x+2500-20x=3900
20x=1400
x=70
125-70=y
y=55

Y=3x+2 scope and graphing

DedPeter [7]

The general rule for a linear equation is y=mx+c where m is the slope or gradient... therefore the slope is 3.

Now we need to get 2 points on the line.

You can easily get the y-int by substituting x=0 into the equation... therefore the y-int is 11... you have one point on the line: (0,11)

Now that you have one point and we know the gradient or slope which is 3, go from the point you have found (0,11) and go up 3 and across 1 to find a second point... then simply rule a line in between the two points.
