A skateboard was reduced in price from $50 to $43. What was the percent decrease?

A) 2%
B) 14%
C) 16%
D) 7%

Step-by-step explanation:

the difference is $7.

100% = $50

1% = 100%/100 = 50/100 = 0.5

$7 is now how many % ?

well, how many times does 1% or 0.5 fit into $7 ?

7 / 0.5 = 14%

so, B is the correct answer.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
