Q. At the school's holiday craft fair, Suzie and her classmates get to make gingerbread houses. Their teacher divides a bag of licorice ropes evenly among the 7 students at the table. Each student gets 5 licorice ropes to decorate the roof of his or her gingerbread house.Which equation can you use to find the number of licorice ropes r that came in the bag?Choices:(A) 7r=5(B) 7r=5(C) r−7=5(D) r+7=5Solve this equation for r to find the number of licorice ropes that came in the bag.___ licorice ropes
Understand the problem: Understand the problem.We need to find the total number of licorice ropes r that were divided evenly among 7 students, with each student receiving 5 ropes. This is a multiplication problem because we are looking for the total amount when we know the number of groups and the number of items per group.
Set up the equation: Set up the equation.Since each of the 7 students received 5 licorice ropes, we multiply the number of students by the number of ropes each student received to find the total number of ropes.The equation is 7×r_per_student=total_ropes, where r_per_student is the number of ropes per student.
Identify the correct equation: Identify the correct equation from the choices.We know that 7 students each got 5 ropes, so the total number of ropes is 7 times the number of ropes per student. The correct equation that represents this situation is:(A) 7r=5, where r represents the total number of ropes.
