I could be wrong here but I’m pretty sure the answer is
P(0.15) because 0.75 x 0.2 is 0.15
$7.22 would be the answer because 70% of 10.31 is what you are looking for which is 7.217 which is rounded to 7.22 I know this is right because I just learned this and I am in advanced math 6th grade.
$81.00
30% of 270 = 0.3 × 270 = 81
F (1) = -2
hope this helps :)
