A 15% percent markup means that the typewriter cost was increased by 15%, or 0.15 by moving the decimal 2 places to the left. If the original price was x, and 15% of it is 0.15*x, we can add them up to get 1.15*x=129.95. Dividing both sides by 1.15, we get x=113 dollars

Sale price=129.95
Mark up=15%
x=at cost price to ABC
Set up proportion:
129.95 x
--------- = ---------- (Got 1 from 100% which is the cost to ABC and 1.15 from 100%
1.15 1 +15% which is the cost to customer then changed to
decimal form.) Cross multiply
129.95=1.15x
129.95/1.15=1.15x/1.15
113=x
Cost to ABC is $113

A cereal company is putting 1 of 4 prizes in each box of cereal. The prizes are evenly distributed so the
lbvjy [14]

Answer:

P(x < 7) = 0.383

Step-by-step explanation:

Given

See attachment for plot

Required

Determine the probability that few than 7 boxes will be needed.

This is represented as:

P(x < 7)

And the solution is:

P(x < 7) = P(x = 4) + P(x = 5) + P(x = 6)

Each probability is calculated by dividing the number of dots by the total dots.

So, we have:

P(x < 7) = \frac{n(x = 4) + n(x = 5) + n(x = 6)}{Total}

From the attached, the formula becomes:

P(x < 7) = \frac{4 + 6 + 3}{4+6+3+4+4+6+3+2+1+2+0+1}

P(x < 7) = \frac{13}{36}

P(x < 7) = 0.361

Example 4
Vesnalui [34]

Answer: Part a: b represents the base fee charged for the "house call" job

m is the hourly rate.

x is the number of hours at the job.

y represents the total cost for the job.

Part b:. The y-intercept is 65

The equation follows y=mx+b

Y= 42x + 65

Part c:. $275

Step-by-step explanation:

The difference between the two total costs, (Camilla 191 - Connor 107)

= $84. That is the rise. The run is the difference in time, 2 hours. 84/2 = 42.

m= 42

42 from 107 to find b, the base fee, 65 This is the y-intercept.

The equation is y= 42x + 65

Quick check using Camilla's bill: 191 = (42)(3) + 65

191 = 126 + 65 True!

Part C:

To find the total cost of the plumber's 5 hour job,

Y = 42(5) + 65

Y= 210 + 65

Y= $275
