A jacket with an original price of $67.80 is discounted 10%. What is the sale price?

$62.82

Step-by-step explanation:

An easy way is to just find out how you need to pay instead of how much you're discounting. So instead of finding how much 10% is and subtracting the original price, you can just find 90% of 67.80 and that would be your final answer.

90%=0.90

0.90 times 67.80 = 62.82

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2
