As given,
Weekly rent of Mr. Thomson is = $104.92
Part A: What is Mr. Thompson's yearly rent (using 52 weeks)?
Rent for 1 week = 104.92
Rent for 52 weeks =
= $5455.84
Part B: What was the average grocery expense in this time period?
Mr. Thomson purchased groceries on 2/18 for $33.45 and on 3/5 for $28.56

The monthly expense for groceries is = $62.01
So yearly expense will be =
= $744.12
D. Because it has more balls.
Answer: 8(x + (-5)) = 2x
Step-by-step explanation: Lets have that "certain" number be x. We wrote an equation to represent the problem.
Advanced ($10): A
Door ($13): D
Money: 10A + 13D = 544 ⇒ 1(10A + 13D = 544) ⇒ 10A + 13D = 544
Quantity: A + D = 46 ⇒ -10(A + D = 46) ⇒ <u> -10A - 10D</u> = <u>-460 </u>
3D = 84
D = 28
Quantity: A + D = 46 ⇒ A + (28) = 46 ⇒ A = 18
Answer: advanced = 18 people, at the door = 28 people
