800,000,000.00+70,000,000.00+6,000,000.00+500,000.00+40,000.00+3,000.00+200.00+10.00+0.00+0.20+0.05
The answer is shown in the picture because it ran afoul of Brainly's "bad word" detector.
Until the 4th visit, GWS has the better cost but after the 4th visit, the cost for Mega is higher.
The greatest value is 8, which means n can be either 8 or any number less than 8.
The inequality would be n is less than or equal to 8, which is written as:
n ≤ 8
1a) 45,000 * 6.2% = 2,790
1b) 45,000 * (6.2% + 1.89%) = 45,000 * 8.09% = 3,640.50
2a) 45,000 * 42% = 18,900
2b) 45,000 * 29% = 13,050
3) I think it would be better to have an increase in Social Security tax now and receive 18,900 as annual pension rather than the decrease in Social Security benefits when she retires.
