Each hotdog cost $1.50 and sodas cost $.50. At the end of the day you made a total of $78.50.You sold a total of 87 hot dogs and
Maru [420]

Answer:

35 hotdogs and 52 sodas were sold.

Step-by-step explanation:

Create equations to represent the problem.

let "d" be the number of hotdogs sold

let "a" be the number of sodas sold

1.5d + 0.5a = 78.50     Equation for money made

d + a = 87                    Equation for items sold

Rearrange d + a = 87 to isolate one of the variables.

a = 87 - d

Substitute a for 87-d into the other equation. Isolate using reverse operations.

1.5d + 0.5a = 78.50

1.5d + 0.5(87 - d) = 78.50     Distribute over brackets by multiplying

1.5d + 43.5 - 0.5d = 78.50    Collect like terms

43.5 + d = 78.50          1.5d - 0.5d is 1d. You don't need to write "1".

43.5 + d - 43.5 = 78.50 - 43.5   Isolate d, subtract 43.5 from both sides

d = 35    Number of hotdogs sold

Substitute d for 35 in the simpler equation

d + a = 87

35 + a = 87     Subtract 35 form both sides to isolate "a".

a = 87 - 35

a = 52      Number of sodas sold

Therefore 35 hotdogs and 52 sodas were sold.

A straight-line graph
Verdich [7]

Given:

A straight-line graph  has gradient 4  and crosses the y axis at (0, −3).

To find:

The equation of the given graph.

Solution:

The slope intercept form of a line is:

y=mx+b            ...(i)

Where, m is the slope of the line and b is the y-intercept.

A straight-line graph  has gradient 4. It means the slope of the line is 4.

m=4

Line crosses the y axis at (0, −3). So, y-intercept is -3.

b=-3

Putting m=4 and b=-3 in (i), we get

y=(4)x+(-3)

y=4x-3

Therefore, the equation of the given line graph is y=4x-3.
