Answer:
why are you in 4 grade my god
Step-by-step explanation:
From 9:00 am to 9:00pm, that's a total of 12 hours,
so 12 of the 20 hours are charged at a rate of 0.25 dollar per hour, and the other 8 hours (20-12=8) are charged at a rate of $0.06 per hour.
the answer is b.
it should be 0.06 though, not 0.6
Step-by-step explanation:
P=$7500
T=2yrs
R=4.2%
now,
CA=P((1–R)^T)/100
=7500(1–4.2/100)^2
then slove it on calculator and you will get the required result
