Final answer:

Erin needs to rent 15 chairs for the cost of the rentals to be the same.

Step-by-step explanation:

To find the number of chairs Erin needs to rent for the cost of the rentals to be the same, we need to set up an equation.

Let x be the number of chairs Erin needs to rent.

For A-1 Rental, the total cost is 1.57x + 63.51.

For Tonka Tents, the total cost is 1.82x + 59.76.

Setting these two equal to each other:

1.57x + 63.51 = 1.82x + 59.76

Subtracting 1.57x and 59.76 from both sides:

3.75 = 0.25x

Dividing both sides by 0.25:

x = 15

Therefore, Erin needs to rent 15 chairs for the cost of the rentals to be the same.
