A sandwich store charges a delivery fee to bring lunch to an office building. One office pays $33 for 4 turkey sandwiches. Anoth
shutvik [7]

Answer:

$12

Step-by-step explanation:

assuming that the cost of delivery is constant irrespective of the number ordered

Let the cost of sandwich be x

First office

$33=4x+c where c is the cost of delivery

Second office

$61=8x+c

These two are simultaneous equation. Subtracting the equation of first office from the second office we obtain

4x=28

Therefore, x=28/4=7

The cost of delivery is 33-(4*7)=33-28=5

Therefore, one sandwich plus delivery costs 7+5=$12

Match the graph with its equation.
victus00 [196]

Answer:

<em>B) -7x + 7y = -49</em>

Step-by-step explanation:

This is a y=x plot/line shifted by 7 units.

This can also be verified plugging in the values of x=0,y=-7 and x=7,y=0. The only equation which satisfies these points in Equation B. These points have been chosen as they're the intercepts of this plot.

2. A dog breeder's pricing model includes a per puppy charge along with a fired service fee. A litter with
pychu [463]

The linear function that models the situation is given by:

C(p) = 100 + 12p

------------------------

A linear function for the cost C of taking care of p puppies has the following format:

C(p) = C(0) + ap

In which:

  • C(0) is the fixed cost.
  • a is the slope, which is the cost per puppy.

------------------------

  • With 6 puppies, it costs $172. With 10 puppies, it costs $220. The slope is given by the <u>change in the output(cost) divided by the change in the input(number of puppies)</u>, thus:

a = \frac{220 - 172}{10 - 6} = 12

Thus:

C(p) = C(0) + 12p

------------------------

The cost of $172 with 6 puppies means that when p = 6, C = 172, and we use this to find C(0).

C(p) = C(0) + 12p

172 = C(0) + 12(6)

C(0) = 172 - 72

C(0) = 100

Thus, the linear model is:

C(p) = 100 + 12p
