3b - a = 45
a = 2b + 40
Solve simultaneously.
3b - (2b + 40) = 45
3b - 2b - 40 = 45
b = 45 + 40
b = 95min (1 hour 35 min)
a = 2 (95) + 40
a = 230min ( 3 hour 50 min)
Answer
17 m^3
Explanation
Volume of a given prism = bh
Where b = base area and h = height of prism
Base area = 1 • 2/2 (b • h /2)
= 1
Height = 17
17 • 1 = 17 m^3
Cost price per bottle of juice = $1.10
Selling price per bottle of juice = $2.50
Profit per bottle of juice = $2.50 - $1.10 = $ 1.40
Let B be the number of bottles needed to sell in one day in order to equal its daily costs.
$1200 = $1.40B
857.14285714285714 = B
858 = B (round off to the nearest bottle)
The company must sell 858 bottles of juice in one day in order to equal its daily cost.
Hope this helps! =)
