Answer: 7
Step-by-step explanation:
Ok, so the discount is given in a percentage, in this case 10%. The sale price is going to reflect 10% of the original price minus the discount, so...
Sale $ = original$ - original $ x .10
If we use some algebra, we can reorganize the equation to solve for the original price...
Sale $ = original$ - original $ x .10
Sale $ = original$ (1 - .10)
Sale $ = original$ x .90
original$ = sale$/.90
So now we can plug in our values
original price = 50/.90
original price = 55.55555 = $55.55 to the nearest nickel

The correct answer is C.
If our equation is y=x+2, the fact that there is no number attached to x means that there is a slope of 1.
Since we are doubling the slope, we would multiply 1 by 2.
1*2=2.
Our equation is now y=2x+2.
I also says to divide the y intercept by 2. The y intercept is the +2 after the x, so divide 2 by 2.
2/2=1
Our equation is now y=2x+1
