Polly bought 12 beach balls for her beach party. She spent $23.64. How much did each beach ball cost?

Number of beach balls Polly bought = 12

Total cost of 12 beach balls = $23.64

Here in order to find cost of one beach ball, we will apply unitary method.

So to find cost of one beach ball we will divide cost of 12 beach balls by 12

So cost of one beach ball = 23.64 / 12 = 1.97.

So cost of one beach ball is $1.97

She spent 1.97 on each beach ball
