Let x and y be the two positive numbers. - Their product is 192: x * y = 192 equation 1
- the sum of the first plus twice the second is a minimum: x + 2y
<span>From the first equation, y = 192 / x.
Substitute that into the second equation:
</span>
x + 2y = x + 2(<span>192/x ) = x + 384/x
</span>f(x) is minimum when f'(x) = 0 and f"(x) > 0
f(x)= <span>x + 384/x
</span>
f(x) = 1-384/x^2
<span>1-384 / x^2 = 0
x^2-384 = 0
x^ 2= 354
x = radical 354 = 18.8 here i'm confused why the number is decimal

Answer:
4 apples are $2.40
That means that 2 apples will be $1.20
And that one apple will be $0.60
$0.60*9= $5.40
She buys 5 more apples each week so she will buy 14 apples this week
$0.60*14= $8.40
Final answer : She will buy 14 apples next week for $8.40
Hope it helped! : )
