Answer:
7.415 ≤ x < 7.425
Step-by-step explanation:
The number x was rounded to 2 decimal places to give 7.42.
Since rounded off to 2 decimal places, the error interval for x is half of 0.01 subtracted from and added to 7.42.
Thus;
7.42 ± (0.01/2)
(7.42 - 0.005),(7.42 + 0.005)
7.415, 7.425
Now, 7.425 will not be included in the internal because approximating it doesn't give 7.42.
Thus,the error interval is;
7.415 ≤ x < 7.425

Answer:
$1920
Step-by-step explanation:
First, find out how much he earns in one week-so $8 times 40 = 320. Then multiply 320 by 6 to get how much earns in 6 weeks which is $1920.
(hope this helps :P)
$90 because 200-10=180 and divide 180 by 2 which is 90.
