A baking club has a bake sale, selling brownies at $1.50 per brownie. Write an equation using two variables to show the relationship between the number of brownies, b, and the total amount of brownies they sold, c. What is the total value of the brownies sold if the club sells 25?
The equation that represents the relationship between the number of brownies sold and the total amount of money earned can be represented as:
c = 1.50b
where "c" represents the total amount of money earned and "b" represents the number of brownies sold.
If the club sells 25 brownies, we can substitute b = 25 into the equation to find the total amount of money earned:
c = 1.50(25) = $37.50
Therefore, the total value of the brownies sold is $37.50 if the club sells 25 brownies.
