Question

A baker sells bread for $5 a loaf and rolls for $1 each. The baker needs to sell $30 worth of baked goods by the end of the day.

Find a linear equation that describes the problem.

An equation for the value of the baked goods is _____ = $30, where b is the number of loaves of bread sold, and r is the number of rolls sold.

Answer 1

5b + r = 30
the cost per item * the number of items sold = the profit

Answer 2

Explanation:

Cost of 1 loaf of bread = $5

Cost of 1 roll = $1

The baker needs to sell both items and it should be worth $30.

To find the linear equation, Suppose, the baker sells “b” loaves of bread and “r” rolls.

Then the total cost of the sales has to be $30.

So, the linear equation will be:

5b + 1r = 30
