larisa [96]

Answer: Total cost is $1.75

Explanation:

Since we have given that

Number of postcards bought by Doug's family= 7

Cost of each postcard including tax = $0.25

Total cost is given by

7\times 0.25=\$1.75

Now, we want to show this in number line :

On the number line put all the number with a difference of 0.25 and run the number line seven times and we get the answer.

Each step is of length 0.25 and there are 7 jumps to reach required answer.

So, after 7 jumps we reach at 1.75 which is the required answer.

Hence total cost is $1.75

Tree pruning company A charges a one-time $100 equipment fee and charges $50 for each tree that it prunes. Tree pruning company
m_a_m_a [10]

Answer:

  • 2 trees ($200 from either service)
  • c=100+50t
  • c=80+60t

Step-by-step explanation:

It can work well to solve problems like this by considering how many times the difference in per-tree costs it takes to make up the difference in one-time costs.

Here the difference of one-time costs is $20, and the difference in per-tree costs is $10, so it takes the pruning of 2 trees for the per-tree cost difference to equal the one-time cost difference (2×10 = 20).

___

The cost equations are ...

  cost = (one-time cost) + (per tree cost) × (number of trees)

  c = 100 + 50t . . . . . company A

  c = 80 + 60t . . . . . . company B

_____

If you use these equations to solve the problem, you want to find t such that the two costs are equal:

  100 +50t = 80 +60t

  (100 -80) = t(60 -50) . . . . . . . subtract 80+50t, factor out t

  (100 -80)/(60 -50) = t . . . . . . . looks a lot like the verbal description above

The difference in fixed price divided by the difference in per-tree cost) is the number of trees required to make costs equal.
