A book costs $35 and marked 15% off. What is the sale price? *

The sale price is $29.75

$29.75

Step-by-step explanation:

Usually, teachers usually teach you a different way to calculate this, but I found a shortcut that is useful:

100 - 15 = 85

Convert 85% into a decimal (0.85)

35 × 0.85 = 29.75

Have a good day :)

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
