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 sold, b, and the total sales from brownies, s. What is the total sales from brownies if the club sells 25? (1 point)

• 8 = 1.5b; $25.00
• 5 = 1.5b; $37.50
• 6 = 1.5s; $25.00
• 6 = 1.5s; $37.50

1 answer

The correct equation using two variables to show the relationship between the number of brownies sold, b, and the total sales from brownies, s is:

s = 1.5b

If the club sells 25 brownies, we can substitute b = 25 into the equation to find the total sales from brownies:

s = 1.5(25) = $37.50

Therefore, the correct answer is:
• 6 = 1.5s; $37.50
