Answer:
Total cost for 2.80 hours = ($255/hr)(2.80 hrs) = $714.
Step-by-step explanation:
Multiply this hourly rate by the elapsed time (2.80 hours):
Total cost for 2.80 hours = ($255/hr)(2.80 hrs) = $714.
We multiply the fraction of 3/4 to the whole number 24 to get the equivalent number of the fraction.
24 * 3/4 = (24 * 3)/4 = 72/4 = 18
3/4 of 24 is 18.
There are 18 blue tiles out of the 24 tiles used.
