Esther buys 6 sweatshirts for $18\$ 18. What is the cost of 1 sweatshirt? First set up a double number line to show how much Esther pays for 6 sweatshirts.
Sweatshirts 6 undefined↦\xrightarrow{\mapsto}
Dollars

Studdy Solution

STEP 1

1. Esther buys 6 sweatshirts for a total of $18.
2. We need to find the cost of 1 sweatshirt.
3. The cost per sweatshirt is constant.

STEP 2

1. Set up a double number line.
2. Determine the unit rate.
3. Calculate the cost of 1 sweatshirt.

STEP 3

Set up a double number line with two lines: one for the number of sweatshirts and one for the cost in dollars.
- Sweatshirts: 0, 1, 2, 3, 4, 5, 6 - Dollars: 0, ?, ?, ?, ?, ?, 18

STEP 4

Determine the unit rate by dividing the total cost by the number of sweatshirts.
Unit Rate=Total CostNumber of Sweatshirts \text{Unit Rate} = \frac{\text{Total Cost}}{\text{Number of Sweatshirts}}

STEP 5

Substitute the known values into the unit rate formula.
Unit Rate=186 \text{Unit Rate} = \frac{18}{6}

STEP 6

Calculate the cost of 1 sweatshirt by solving the division.
Unit Rate=186=3 \text{Unit Rate} = \frac{18}{6} = 3
The cost of 1 sweatshirt is:
$3\boxed{\$3}
