Answer:
$94.5
Step-by-step explanation:
What is 80% MORE than $52.50?
just multiply $52.50 by 1.80 = $94.5
why multiply by 1.80? ---- because we are adding 80% of 52.5 + the original price... that is why its 1.80.
It would be 3/20 mile because you have to multiply 1/5 by 3/4, which would give you grand total of 3/20 mile.
