No, the amount of candy bars sold is not proportional to the money Isaiah received.
Unit rate is the rate of two different units, with denominator as 1. For illustration, kilometer/ hour, cadence/ sec, long hauls hour, payment/ month, etc. computation is presumably the most introductory and ancient branch of mathematics and is relatively generally used in our day- to- day life.
In a unit rate, the denominator is always 1(one). So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1(one). For illustration, if 50(fifty) km is covered in 5.5 hours, the unit rate will be 50(fifty) km 5.5 hours = 9.09 km/ hour.
When you divide the money received by candy bars sold you do not get the same unit rate.
Hence, The amount of candy bars sold is not proportional to the money Isaiah received.
