Sophia bought 9 red peppers for $5.40.

Question

Find the unit rate. Then use the unit rate to write an equation relating the cost in dollars c to the number of red peppers p.

Answer 1

To find the unit rate, we divide the total cost by the number of red peppers purchased.

Unit rate = Total cost / Number of red peppers

Unit rate = $5.40 / 9 = $0.60

The unit rate is $0.60 per red pepper.

To write an equation relating the cost in dollars c to the number of red peppers p, we can use the unit rate.

c = p * unit rate

c = p * $0.60
