c) Write and solve an equation to find out how long they worked if her bill was $140.
Equation:_________________________
Solution:_______________

Answer 1

Explanation:

a)

42 x 1 = 42

42 x 2 = 84

42 x 3 = 126

42 x 4 = 168

42 x 5 = 210

I don't know how long you table has to be so I just went to 5.

b) I don't really understand this part, so don't take my word for it, but I THINK the answer is 42x. I may be wrong.

c) Your equation for this would be 35 + 42x = 140.

This is you equation because the fee was $35 and she paid $42 per hour, and that all added up to be $140.

Now the way you would solve this equation is, you would rewrite the equation:

35 + 42x = 140

Step 2: Simplify both sides of the equation.

42x+35=140

Step 3: Subtract 35 from both sides.

42x + 35 − (35)=140 - (35)

42x = 105

Step 4: Divide both sides by 42.

42x/42 = 105/42

x = 5/2 or 2.5

I hope that this helped.
