Why are the solutions to the proportions StartFraction 50 over x EndFraction = StartFraction 10 over 20 EndFraction and StartFra
ction 10 over 50 EndFraction = StartFraction 20 over x EndFraction the same? because both result in the equation 20 x = 500, which simplifies to x = 25 because both result in the equation 20 x = 500, which simplifies to x = 250 because both result in the equation 10 x = 1,000, which simplifies to x = 10 because both result in the equation 10 x = 1,000, which simplifies to x = 100
1. The withdrawals adds up to 291+99+150+12= 552 500-552= -52 2. The bus pass which cost $150. 3.1000-552= $448 left 4.1000-552-300-150=$-2 left. Withdrawal had happened.
