Answer:
Quadratic
Step-by-step explanation:
2705/500 = 5.41
10,818/1000 = 10.818
24 341/1,500 =24.227
43,273/2000 = 21.6365
67,613/2500 = 27.0452

14000+7x=35x (x being the number of books) solve for x and you have your answer. 14000=35x-7x=28x therefore x=14000/28=500 so he needs to sell 500 books before he breaks even.
Answer:
the sales tax percent is therefore: 7.75%
Step-by-step explanation:
The sales tax she paid is $69.75, for a sofa whose sale price is $899.99.
Since $69.75 is the unknown (x) percent of $899.99, then we write this statement in math terms as:
69.75 = x * 899.99
solving for x we get:
x = 69.75 / 899.99
x = 0.0775
this is the decimal form of the percent, and in order to write it as percent, we multiply it by 100:
the sales tax percent is therefore: 7.75%
So there are 2 numbers
pretend the smaller number is x, so the larger number must be 2x because it's twice as large
so 2x+x equals 54
simplifies to 3x=54
x= 18
the smaller number is 18 and the larger one is 36 (because 36 is 18 x 2)
