Answer:

1 – cosθ/1 + cosθ = secθ – 1/secθ + 1

Here, we know that secθ = 1/cosθ

Now,

1 – cosθ/1 + cosθ = secθ – 1/secθ + 1

1 – cosθ/1 + cosθ = 1/cosθ – 1 ÷ 1/cosθ + 1

1 – cosθ/1 + cosθ = 1 – cosθ/cosθ ÷ 1 + cosθ/cosθ

1 – cosθ/1 + cosθ = 1 – cosθ/1 + cosθ

Hence Proved!!

Greeley [361]

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! =)
