Answer:

$455

Step-by-step explanation:

Minimum unemployment benefit in Texas is $69 per week and the maximum is $521.

In order to determine unemployment benefits in Texas, you must first calculate total earnings for the last quarter = 13 x $1,750 x 1/2 = $11,375

Now, you divide that amount by 25, so $11,375 / 25 = $455. Since that amount is below the maximum unemployment benefit per week, then Morgan is going to receive $455.

Zarrin [17]

x+y=131973

x=y+473

2y+473 = 131973

2y = 131500

y= 65750

x= 65750 + 473 = 66223


65750 + 66223 = 131973

 so one country is  65750 and the second country is 66223
