Soro bought a $50.00 bus card at the beginning of the week. each bus ride costs $2.50. he needs to have at least $20.00 on
his card at the end of this month. to determine how many bus rides he can take between now and the end of this month, soro
wrote and solved the following inequality:
50 - 2.5x_> 20
-2.5x_> -30
x_> 12
what error, if any, did soro make when writing or solving this inequality?
a: soro's original inequality should have been 50-2.5x5 20.
b: soro should have added 2.5 to each side for his first step.
c: soro should have reversed the inequality symbol when using the division property of inequality.
d: soro's work shows no errors.
