Carla is age 32. how many quarters of coverage does she need to be fully insured
never [62]
According to my research, And I would take this with a grain of salt since I am not a insurance rep . You can earn up to four quarters of coverage each year. In order to be fully insured for Social Security Disability purposes, you must have earned at least one quarter of coverage per year for each year since you turned 21 years old. A minimum of six quarters of coverage is needed to be fully insured at any age so maybe Six quarters, at least according to SSD .
Hope I helped or shed some light !.

Gem and her three friends are going on a holiday. There is a buy 2 get one free offer on plane tickets. Tickets cost £600 each.
VLD [36.1K]

Answer: £450

Step-by-step explanation:

If they bought 2 tickets, they could get an extra ticket for free. As there are three of them, they would buy 2 tickets, get one for free and then buy another ticket to make it four.

In that case they would have only paid for 3 tickets.

The total cost of 3 tickets is:

= 600 * 3

= £1,800

The 4 of them would therefore have to pay:

= 1,800 / 4

= £450
