The answer is B.4 (if you substitute the x with the 4 you’ll get 0)
Answer:
Rate: 11%
Step-by-step explanation:
Interest formula.
Interest = Principal * Rate * Time
121 = 1100 * r * 1
Simplify equation to equal 121/1100 = r
There the rate is equal to 121 divided by 1100 which is 0.11.
To get the percent multiply my 100.
There the rate is 11%.
Proof:
1100 * 11 percent is equal to $121.
since each bottle is $3, it would be 20-3x=y. Y is the change she receives and x is the amount of bottles she buys.
Hope this helps :)
It would be 2*(5^2)
(2 multiply to (5 rise to the power of 2))
Hope that help.
The first step would be to cross multiply:
x 4
-- = ---
2 12
12x = 8.
Solve the equation from there. :)
