5(5+x) = 6(6+4)
25+5x = 60
5x = 35
x = 7
-----------------
3(3+5) = 4(4+x)
24 = 16 + 4x
4x = 24-16
4x = 8
x = 2

Determine the inequality
Assume she wants to buy n CDs.
If 1 CD costs $10, then n CDs costs 10n.
So, the inequality is:
<em>We used </em>
<em> because the amount she wants to spend cannot exceed 30</em>
Divide both sides by 10, to solve for n
Answer:
$34.83
Step-by-step explanation:
First convert 3/4 to decimal form: 3/4 = 0.75
Create a proportion using similar rates:
$2.75 / 0.75 lb = x / 9.5 lb
where "x" represents the price of the 9.5 lbs of grapes we need to find.
Solve for x by multiplying both sides by 9.5 lb to isolate x completely
2.75 * 9.5 / 0.75 = x
Therefore x = $34.83
