We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.

A. Independent variable: number of rubber stamps n sold. Dependent variable: F(n), the total sales.

B. Only whole numbers. It is impossible to have negative and/or fractional stamps.

C. F(n) = $4.95n, which is 4.95 times n.

So, plugin 5 for n

f(5)= \$4.95(5)

Eight hot dogs and seven hot dog rolls cost $\$13.60$. Seven hot dogs and eight hot dog rolls cost $\$13.40$. How much, in dolla
Maru [420]

Answer:

$1.80

Step-by-step explanation:

Let the cost of a hot dog = x

The cost of a hot dog roll = y

Eight hot dogs and seven hot dog rolls cost $\$13.60$.

8x + 7x = $13.60..... Equation 1

Seven hot dogs and eight hot dog rolls cost $\$13.40$.

7x + 8x = $13.40...... Equation 2

Combining both Equation

8x + 7x = $13.60..... Equation 1

7x + 8x = $13.40...... Equation 2

Eliminating x

Multiply 1 by 7

Multiply 2 by 8

56x + 49y = 95.2..... Equation 3

56x + 64y = 107.2 ..... Equation 4

Subtracting 4 from 3

-15y = -12

y = -12/-15

y = 0.8

Cost of one hot dog roll = $0.8

Solving for x

8x + 7x = $13.60

8x + 7(0.8) = 13.60

8x + 5.6 = 13.60

8x = 13.60 - 5.60

8x = 8.0

x = 8.0/8

x = 1.

Cost of one hot dog = $1.0

The cost in dollars of a hot dog and a hot dog roll cost combined is

x + y

= $1 + $0.8

= $1.80
