Iteru [2.4K]

Answer:

2027 = $122.25

2016 = $48

Step-by-step explanation:

Find 1% of 75

75 / 100 = 0.75

multiply by 9

0.75 * 9 = 6.75

So that's $6.75 each year

Now, lets find our answers for 7 years.

6.75 * 7 = $47.25

75 + 47.25 = $122.25

<u>The stock will be $122.25 in 2027</u>

Now for 2016.

$6.75 * 4 = $27

$75 - $27 = $48

<u>The stock was $48 in 2016</u>

ra1l [238]

Answer:

Angle 2: 110 degrees, 1 and 2 would have to be the same for the lines to be parallel

Angle 3: 70 degrees angle 3 would have to be the complement to angle 1, so 1+3=180 and 70*3=180, so 3=70 degrees

Angle 4: 70 degrees, 3 and 4 have to be the same opposite angles for the lines to be parallel

The cost for the raw materials of marble countertops, can be represented by the function , where is the area of the countertops.
Lady_Fox [76]

Answer:

m(c(a)) = 4.8875a

Step-by-step explanation:

The missing parameters are:

c(a) = 4.25a --- Cost of marble countertops

m(c) = 1.15c --- Cost of retail markup

Required

The cost of marked up price

This implies that we calculate m(c(a))

We have:

c(a) = 4.25a

m(c) = 1.15c

m(c) = 1.15c can be written as:

m(c(a)) = 1.15*c(a)

Substitute: c(a) = 4.25a

m(c(a)) = 1.15*4.25a

m(c(a)) = 4.8875a

Hence, the cost of marked up price is: m(c(a)) = 4.8875a
