after a 30% reduction, you purchase a dictionary for $30.80 what was the dictionary price before the reduction

Well the original price would be $44

Step-by-step explanation:

So make an equation

Lets make X stand for the price before the deduction

so x-x(0.3)=30.80

Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change

Now just solve the equation

You’ll get 44.

Stacy's present age = x

Laura's present age = 8 + x

Laura's age next year = (8 + x) + 1

Also, Laura's age next year = 3x

Therefore,

3x = (8 + x) + 1

3x = 9 + x

3x - x = 9

2x = 9

x = 9/2

x = 4.5

Laura's present age = 8 + x = 8 + 4.5 = 12.5
