5% = .05
.05 x 300 = 15
So part A that's 15 fewer cars.
285 x (1/5) = 57 NASCAR cars
285 x (1/3) = 95 WWII vintage cars
285 - (57 + 95) = 285 - 152 = 133
So part B that's 133 cars that are neither NASCAR or WWII
Answer:
The difference in the numbers of cars manufactured in August and September is 15 and cars manufactured in September were neither NA SCAR model cars nor world war II vintage model cars are 133
Step-by-step explanation:
Cars manufactured in August = 300
In September, action wheels manufactured 5 %fewer models cars than in August.
So, cars manufactured in September = [tex]300-5\% \times 300[/tex]
= [tex]300-\frac{5}{100} \times 300[/tex]
= [tex]285[/tex]
Part A)The difference in the numbers of cars manufactured in August and September = 300-285 = 15
Part B)
Of the model cars manufactured in September, 1/5 were models of NA SCAR cars and 1/3 were World War II vintage models.
No. of NA SCAR cars = [tex]\frac{1}{5} \times 285 =57[/tex]
No. of World War II vintage models. cars = [tex]\frac{1}{3} \times 285 =95[/tex]
So, cars manufactured in September were neither NA SCAR model cars nor world war II vintage model cars = 285-(95+57) =133
Hence the difference in the numbers of cars manufactured in August and September is 15 and cars manufactured in September were neither NA SCAR model cars nor world war II vintage model cars are 133
