Answer:
the cost of each book = $24
Step-by-step explanation:
(if all the books have the same price)
Let x be the price of one book
“She had $157 and After buying 6 books ,she was left with 13$“ means
“157 = 6x + 13”
now we have an equation to solve :
157 = 6x + 13
⇔ 157 - 13 = 6x
⇔ 144 = 6x
⇔ 24 = x
You have to figure out what 48 percent of 70 is.
Use the formula percent/of = x/100.
So, 48/70 and x/100 you cross multiply the numbers; 48*100 and 70*x and end up with 70x=4800.
Divide both sides by 70, which gives you 68.57.
Round the number up to 69 percent.
The first step would be :
E) 3x + (2x + 4) = -7
Answer:

Answer:
Step-by-step explanation:
We can plug this into a formula and get
the .9075 comes from 1 - the depreciation value of 9.25% which converts to .0925 in decimal form.
? is what we are trying to solve for.
We can divide both sides by 19,700 and we get
so ? is about 13.
