i think you have to multiply those. thats it
Answer:
$1.50 dollars per bag and at that rate it would be $7.50 for 6 bags of chips
Step-by-step explanation:


so the ODE is indeed exact and there is a solution of the form
. We have




With
, we have

so

75.09 = seventy- five and nine-hundredths
Note that
108° = 90° + 18°
so
sin(108°) = sin(90° + 18°) = sin(90°) cos(18°) + cos(90°) sin(18°) = cos(18°)
Then
sin²(108°) + sin²(18°) = cos²(18°) + sin²(18°) = 1
by the Pythagorean identity.
