Given the statement:
Wendy noticed that out of 420 vehicles that drove by her house, 56 were SUVs.
Determine how many SUVs can Wendy expect if 2,100 vehicles drive by her house.
Solution:
Find first the percentage of SUV's that passed by her house. To do so divide 56 by 420.
= 56/420
= 0.13333…
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= (0.13333)(100)
= 13.33%
13.33% of the vehicles that passed by her house are SUVs, hence we multiply 0.1333 by 2100 to determine the number of SUVs.
= (0.13333…)(2100)
=280
FInal answer:
= 280 SUVs
