Answer:
x+27 ≤ 40
You cannot buy more than 13
If you buy 15 they will not fit
Step-by-step explanation:
To determine the number of CD's that will still fit
The number of CD's must be less than or equal to 40
You already have 27.
Let x be the number you are going to buy
x+27 ≤ 40
Subtract 27 from each side
x+27-27 ≤ 40
x ≤ 13
You cannot buy more than 13
If you buy 15 they will not fit
Answer:
$145.80
Step-by-step explanation:
The original cost of the product was $90. There was a 162% markup. In order to get the selling price, I like to take away 100 percent and simply add original price+(original price*62%). After taking away 100%, I am left with 62%. I then multiply the original cost ($90) by the remaining percent (62%), getting 55.8. Following the steps that I originally wrote, I now add 90 to 55.8, getting 145.8.
It depends on how many shirts you have
Answer:
15/56x^(-4/7) + 32x^3 + 6.
Step-by-step explanation:
Using the rule for algebraic differentiation:
If y = ax^n, dy/dx = anx^(n-1).
So :
If y = 5/8x^3/7 + 8x^4 + 6x - 9
dy/dx = 5/8* 3/7 x^(3/7-1) + 8*4 x^(4-1) + 6x(1-1)
= 15/56x^(-4/7) + 32x^3 + 6.
