Abby and Lexi each open a savings account on the same day. Both accounts accrue simple interest. The function f(t) = 10t + 500 models the amount of money in Abby’s account over time. The function g(t) = 11.25t + 450 models the amount of money in Lexi’s account over time. Select all the statements that are true of this situation.

• Abby opened her account with more money and accrues interest at a greater rate.

• Abby opened her account with more money and accrues interest at a lesser rate.

• Abby opened her account with less money and accrues interest at a lesser rate.

• Lexi opened her account with less money and accrues interest at a lesser rate.

• Lexi opened her account with less money and accrues interest at a greater rate.
