Studdy Solution

STEP 1

1. Kimmy bought a 5-kilogram can of peanuts.
2. The total cost of the peanuts is \$4.50.
3. We need to find the cost per kilogram, i.e., the unit price.

STEP 2

1. Define the unit price.
2. Calculate the unit price.
3. Compare the calculated unit price with the given options.

STEP 3

Define the unit price as the cost per kilogram of peanuts.

STEP 4

Calculate the unit price by dividing the total cost by the total weight.
Unit Price=Total CostTotal Weight\text{Unit Price} = \frac{\text{Total Cost}}{\text{Total Weight}}

STEP 5

Substitute the given values into the formula.
Unit Price=$4.505 kg\text{Unit Price} = \frac{\$4.50}{5 \text{ kg}}

STEP 6

Perform the division to find the unit price.
Unit Price=$0.90 per kg\text{Unit Price} = \$0.90 \text{ per kg}

STEP 7

Compare the calculated unit price with the given options: - A: \$0.05 / kg - B: \$0.45 / kg - C: \$0.50 / kg - D: \$0.90 / kg
The correct option is:
D $0.90/kg\boxed{D \, \$0.90 / \text{kg}}
