An equation was used to predict possible sales of phones for 6 months. The actual sales of phones are also listed. Actual sales

Ugo [173]

The residue in each case is the difference between actual and predicted sales. Thus:
55 - 40 = 15
150 - 150 = 0
325 - 300 = 25
510 - 500 = 10
800 - 780 = 20
1000 - 990 = 10
These add up to be:
15 + 25+ 10 +20 +10
= 80

Using a graph, table of values, and/or equations solve the following problem.

katovenus [111]

Answer:

$L= 117.0$

Step-by-step explanation:

Represent the sofa with S and the love seat with L.

So, we have:

$S + L = 351$ --- Total Cost

$S = 2L$

Required

Determine the value of L

Substitute 2L for S in the first equation.

$2L + L = 351$

$3L= 351$

Divide both sides by 3

$\frac{3L}{3}= \frac{351}{3}$

$L= \frac{351}{3}$

$L= 117.0$

Hence, a love seat costs 117.0

Using Graph

See attachment for graph

S is plotted on the y-axis and L is on the x-axis.

The green line represents $S + L = 351$ while the orange line represents $S = 2L$

When the line of the graph is traced to the x-axis, we have:

$L= 117.0$
