We are given

where
y is the cost in dollars
x is distance in dollars
now, we can find derivative



so,

So,

Answer:
RSU = 75.2°
Step-by-step explanation:
this is because:
⇒ RSU = RST + TSU
⇒ RSU = 48 + 27.2
⇒ RSU = 75.2°
Hence proved
To do this problem you use is/of=percent/100
So:
320/750=x/100
cross multiply
32,000=750x
divide both sides by 750
x=42.66 repeating
ANSWER: X=42.66 REPEATING
