Reels produced at 800 per day but production cut by 1/5. They have an order for 20,000 reels. Can they produce enough in 30 days
Neko [114]

The company can not produce enough reels.

Step-by-step explanation:

Reels produced per day = 800

Production cut = 1/5

Let, the daily production be 1.

therefore,

New per day production = 1-\frac{1}{5}=\frac{5-1}{5}

New per day production = 4/5

Therefore,

4/5 of 800 = New no. of reels produced per day

\frac{4}{5}*800 = New no. of reels

640 = New no. of reels

New. no of reels produced per day = 640

Reels produced in 30 days = 640*30 = 19200

The company can not produce enough reels.

SOMEONE PLEASE HELP ME! I've been stuck on this for over 3 hours and i really need help! I'm offering 40 points!
Ne4ueva [31]

Answer:

x\geq 8.6

Step-by-step explanation:

This problem requires subtraction, then division.. The first step is to add 9.5 to each side of the inequality. This isolates 6x on one side and makes the equation easier to understand:

-9.5+9.5+6x\geq 42.1+9.5\\6x\geq 51.6

Next, you need to divide each side by 6 to get your answer:

\frac{6x}{6}\geq  \frac{51.6}{6} \\x\geq 8.6

As a little bonus tip, if you ever end up dividing each side by a negative number, you MUST reverse the sign.
