X = [ (i sqrt46) / (2) ] ; - [ (i sqrt46) / (2) ]
Of the two rows you ought to choose the top one
48 - 3x > 10
The second row makes the bottles grow. I wish this were true, but it is not.
After x gets to 13, she has dropped down below where she does not need to shop for more bottles.
48 - 3x > 10 Add 3x to both sides.
48 > 10 + 3x Subtract 10
38 > 3x Divide by 3
12 . 66666 So she can finish the 13th bottle but when she does, she has to go out and get more.
Answer:
a. $395
b. $(350 + 0.15x)
Step-by-step explanation:
Her income in a week can be written as;
$350 + 15% of sales
a. In the case of $300 sales in a week
Mathematically, that would be;
$350 + 15% of $300
$350 + (15/100 * 300)
$350 + $45 = $395
b. In the case of $x in sales
= $350 + 15% of x
= $350 + (15/100 * x)
= $350 + 0.15x
= $(350 + 0.15x)
The answer would be 1 solution
