Her profit is $4.80 :)
$7.20•2=$14.40
24 pens • $0.80 =$19.20
$19.20-$14.40=$4.80 profit :)
Answer:
<h2>290 in²</h2>
Step-by-step explanation:
From the net:
S.A. = 2(25 in²) + 4(60 in²) = 50 in² + 240 in² = 290 in²
From the model:
The formula of a Surface Area of a rectangular prism:
S.A. = 2(lw + lh + wh)
l - length
w - width
h - height
We have l = 5 in, w = 5 in, and h = 12 in. Substitute:
S.A. = 2(5 · 5 + 5 · 12 + 5 · 12) = 2(25 + 60 + 60) = 2(145) = 290 in²
√9 = 3 and is rational
Its C
