The surface area of what shape exactly?
3x + 11.63 = 20
3x + 11.63 - 11.63 = 20 - 11.63
3x = 8.37
by subtracting the 11.63 from both sides, this tells us how much the grapes cost....not per lb., but for the total of all the grapes.
Answer:
$3
Step-by-step explanation:
Started with $20 Sold for $24 Bought it for $25 Then sold it for $28
so, $24 -$20= so she made $4.
then she bought it for $25-$24= so she only made $1
Finally she sold it for $28-$25 so she made a total of $3
Y = 0.8597(60) + 73.4728
y = 124.9468
About 125 g
