To find the percent you have to find what amount is the sale for that you do
40-25=15
then you put that over the original
15/40
when you divide those you get 37.5%

dlinn [17]

Answer:

a) 20 more people said their favorite vehicle color was blue compared to those who said white.

b) 55 people said their favorite vehicle color was either black or silver

Step-by-step explanation:

(a). How many more people said their favorite vehicle color was blue compared to those who said white explain?

250 people

32% said blue. 32% of 250 is 0.32*250 = 80

24% said white. 24% of 250 is 0.24*250 = 60

80 - 60 = 20

20 more people said their favorite vehicle color was blue compared to those who said white.

(B) how many people said their favorite vehicle color was either black or silver ?

18% said black, 4% said silver.

18 + 4 = 22% of 250 = 0.22*250 = 55

55 people said their favorite vehicle color was either black or silver

Which is the simplified form of the expression 3(7/5x+4) - 2(3/2 - 5/4x)?
Kruka [31]

Answer:

B. \frac{67}{10} x + 9

Step-by-step explanation:

Simplify the expression. Remember to go by the order of operations, or PEMDAS.

1) First, distribute the numbers outside of the set of parentheses to the terms inside the set of parentheses next to them. Then, simplify the fractions.

3(\frac{7}{5} x + 4) -2 (\frac{3}{2} -\frac{5}{4} x)

\frac{21}{5}x + 12  - \frac{6}{2} + \frac{10}{4} x

\frac{21}{5} x + 12 - 3 + \frac{10}{4} x

2) Finally, combine like terms. (This means to add or subtract constants and to add or subtract terms with the same variables.) You may need to convert terms to the same denominator in order to do so easier. Then, reduce the fraction.

\frac{21}{5} x + 9 + \frac{10}{4}x \\\frac{84}{20}x + \frac{50}{20}x + 9 \\\frac{134}{20}x + 9 \\\frac{67}{10}x + 9

Thus, the answer is \frac{67}{10} x + 9.
