Answer: Erin needs to rent 15 chairs
Explanation:
Hi, we have to write an equation for each rental's cost.
A-1 Rental charges $1.33 per chair, plus $64.42 for the tent.
Tonka Tents charges $1.58 per chair, plus $60.67 for the tent.
- A-1 Rental's Cost = 1.33x+64.42
- Tonka Tents Cost = 1.58x+60.67
Where x is the number of chairs.
If both costs are equal:
A-1 Rental's Cost = Tonka Tents Cost
So:
1.33x+64.42 = 1.58x+60.67
Solving for x:
64.42-60.67 = 1.58x-1.33x
3.75 = 0.25x
15 =x
