Kenny has a sub shop. He sells subs for $5.50 each. A man comes in to buy subs for a party. If the man pays $66.00 for his order, how many subs did he buy? Define the variable, write an equation to represent the situation, and solve the equation.

Pls help!!!

Answers

Answer 1

Answer:

variable: x = # of subs

equation: 5.5x = 66

solution: 12 subs

Step-by-step explanation:

Variable = x. x = # of subs

5.5x = 66 (5.5 times # of subs = total for the order)

5.5x/5.5 = 66/5.5

x = 12

Answer 2

Answer:

66.00/5.50= 12

Answer:

A- 24m

B- 18.9

C. 11.4

Total- 54.3

Step-by-step explanation:

Answer:

41.7 square meters

Step-by-step explanation:

First, rectangle A:

4 x 6 = 24 square meters

Second, rectangle B:

We know the length of this section is 3.5m. For the height/width, we can look at rectangle C. The height of C is 3.8m, and we see the part of C that is NOT part of B is 2m long. So we subtract 2 from 3.8 to find the height of B.

3.8 - 2 = 1.8m

Then, for the area of B:

3.5 x 1.8 = 6.3 square meters

Third, rectangle C:

3 x 3.8 = 11.4 square meters

Add up areas of A, B, C:

24 + 6.3 + 11.4 = 41.7 square meters

Simplify the expression.

Therefore, Alana earns $23 for walking 23 km. Therefore, Alana walks 73.5 km if she earns $60.

What is equation?

An equation is a mathematical statement that shows that two expressions are equal. It usually consists of variables, coefficients, and mathematical operations such as addition, subtraction, multiplication, and division. An equation can be solved to find the value of the variable that makes the statement true. Equations can be represented using symbols, such as the equals sign (=), or written out in words. Equations are used in many areas of mathematics and other fields, such as physics, engineering, and finance, to model and solve real-world problems.

Here,

To find the amount of money Alana earns for walking 23 kilometers, we can use interpolation method on the given table.

First, we need to find the interval in which 23 km falls, which is between 4 km and the unknown value x.

Next, we need to find the corresponding interval for the amount earned, which is between 7 dollars and an unknown value y.

Using the formula for interpolation, we can find the value of y as follows:

y = 7 + [(23-4)/(x-4)] * (16.5-7)

Simplifying this equation and solving for x, we get:

x = 37 km

Therefore, Alana earns $23 for walking 23 km.

To determine how far Alana walks if she earns $60, we can use extrapolation method on the given table.

First, we need to find the interval in which 60 dollars falls, which is between 16.5 dollars and an unknown value z.

Next, we need to find the corresponding interval for the distance walked, which is between 10 km and an unknown value w.

Using the formula for extrapolation, we can find the value of w as follows:

w = 10 + [(60-16.5)/(z-16.5)] * (x-10)

Simplifying this equation and solving for z, we get:

z = 73.5 dollars

Therefore, Alana walks 73.5 km if she earns $60.

It's worth noting that interpolation and extrapolation methods are approximations and may not be completely accurate.
