Final answer:
The value of the expression 90.5y-13.6x when x=20 and y=100 is 8778.
Step-by-step explanation:
The value of the expression 90.5y−13.6x when x=20 and y=100 can be calculated by plugging in the given values for x and y into the expression. We multiply 90.5 by 100 and 13.6 by 20 and then subtract the latter from the former:
90.5 × 100 = 9050
13.6 × 20 = 272
Therefore, the value of the expression is 9050 − 272, which equals 8778.

272
=9050−272
Now, subtract 272 from 9050:
=
8778
=8778
