Christopher is choosing between two cell phone plans that offer the
same number of free minutes. T-Mobile's plan is $39.99 with additional
minutes costing $0.45 each. Verizon's plan is $44.99 with additional
minutes costing $0.40 each. Which equation will let you know how many
additional minutes, a, it will take for the two plans to cost the same? *
39.99a +0.45 = 44.99a + 0.40
39.99 a + 0.45 = 44.99a -0.40
39.99 +0.45a = 44.99 + 0.40a
39.99 + 0.45a = 44.99a +0.40
