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?(1 point)
A: c=1.5b; $25.00
B: b=1.5c; $25.00
C: b=1.5c; $37.50
D: c=1.5b; $37.50
D: c=1.5b; $37.50
The correct answer is:
A: c=1.5b; $25.00
To show the relationship between the number of brownies, b, and the total amount of brownies sold, c, in terms of an equation, we can use the equation c=1.5b. This equation states that the total amount of brownies sold, c, is equal to 1.5 times the number of brownies, b.
If the club sells 25 brownies, we can substitute b=25 into the equation to find the total value of the brownies sold, c:
c=1.5*25
c=37.5
So, the total value of the brownies sold would be $37.50. However, since the options only ask for the value in dollars, the answer would be $25.00.
To write an equation showing the relationship between the number of brownies, b, and the total amount of brownies sold, c, we need to consider the price per brownie.
The equation should be: c = b * price per brownie
In this case, the price of each brownie is $1.50. So the equation becomes: c = 1.5b.
Now, to find the total value of the brownies sold when the club sells 25 brownies, we can substitute the value of b into the equation:
c = 1.5 * 25
c = 37.5
Therefore, the correct answer is:
D: c = 1.5b; $37.50
