Aspen has 306 green beads and 210 silver beads. For every 5cm of a belt that Aspen sews, they use 40 green beads and 24 silver beads. After how many centimeters of the belt will Aspen have equal numbers of green and silver beads left?cm
Q. Aspen has 306 green beads and 210 silver beads. For every 5cm of a belt that Aspen sews, they use 40 green beads and 24 silver beads. After how many centimeters of the belt will Aspen have equal numbers of green and silver beads left?cm
Setting up equation: Let x be the number of centimeters of belt needed for the beads to be equal. Remaining green beads = 306−540xRemaining silver beads = 210−524xLet's set the two expressions equal:306−540x=210−524x
Equation solving: Solve the equation to find the value of x.Subtract both sides of the equation by 210:306−540x−210=−524x96−540x=−524xNow, add both sides of the equation by 540x: 96=540x−524x96=516x
Solve for x: Multiply both sides of the equation by 165:96×165=516x×1656×5=xx=30 After 30 centimeters of the belt, Aspen will have an equal number of green and silver beads left.
