Answer:
$ 10.50
Step-by-step explanation:
we can use a proportion to answer this question
25 : 100 = x : 7
x = (25 * 7)/100 = $1.75 (value of the discount)
Final price = 7 - 1.75 = $5.25
she bought two = 5.25 x 2 = $10.50
1.07 = 1 + 0.07 = 100% + 7%
<h3>The growth rate is 7%</h3>
An example would be say you start off with 100 items. Multiply this with 1.07 and you should get 107 as a result, which is an increase of 7% (note how 7% of 100 = 7)
5x-6=10-3x
5x=10-3x+6
5x+3x=10+6
8x=16
x=16÷8
x=2
Very sorry if the answer is wrong but im quite sure that the answer is (D)
proof:
(5×2)-6=10-(3×2)
10-6=10-6
4=4
So if my mental culculations are correct, the answer is (D)
