Q. Randy charges his tenants \$400 each month to rent his houses plus \$600 security deposit. In the new year, the property taxes increased on the area where he rents so as a result he must increase the rate of change by \$25 to ensure his profits are not harmed. What equation best represents how much his tenants will now have to pay?
