<u>Answer:</u>

  • The total expenses is $156 is the total necklaces sold is 4.

<u>Step-by-step explanation:</u>

We know that:

  • x = Necklaces created and sold
  • 140 + 4(x) = Total cost
  • 39x = Profit = Total cost
  • Profit = Total cost

Work:

  • 140 + 4x = 39x
  • => 140 = 39x - 4x
  • => 140 = 35x
  • => x = 140/35
  • => x = 4

Now, let's substitute the value of x into any equation to find the total expenses and sales.

  • 140 + 4x
  • => 140 + 4(4)
  • => 156

Hence, <u>the total expenses is $156 is the total necklaces sold is 4.</u>

<u>Hoped this helped.</u>

Answer:

Nina would have total expenses and sales $156 after selling 4 necklaces.

Step-by-step explanation:

Let <em>x</em> represent the amount of necklaces made and sold.

The initial cost was $140 and it costs $4 to produce one necklace. Hence, the total cost after producing <em>x</em> necklaces can be represented as:

\displaystyle 140 + 4x

Each necklace sells for $39. Hence, the total profit after selling <em>x</em> necklaces can be represented as:

\displaystyle 39x

To break even, the total cost and profit must be equivalent. Hence:

\displaystyle 140 + 4x = 39x

Solve for <em>x: </em>

<em />\displaystyle \begin{aligned} 140 + 4x & = 39x \\ \\ 140 & = 35x \\ \\ x & = 4 \end{aligned}<em />

<em />

Hence, the break even, Nina would need to sell four necklaces.

And the total expenses/profit would be:

\displaystyle \$39(4) = \$156

In conclusion, Nina would have total expenses and sales $156 after selling 4 necklaces.

It takes William 45 minutes to weed the garden. It takes his younger sister May 75 minutes to do the same job. If they work toge
marshall27 [118]

Answer:

B. 28 minutes

Step-by-step explanation:

According to the given statement,

William weeds the whole garden in 45 minutes, then in one minute he will weed 1/45 of the garden

and

similarly, 1/75 of the garden in one minute.

When they both will work together, they will weed (1/45+1/75) of the garden in one minute

Solving the equation:

= \frac{1}{45}+ \frac{1}{75}\\= \frac{75+45}{3375}\\ =\frac{120}{3375}\\ = 0.036

Garden weeded in one minute by both = 0.036

So, number of minutes to weed whole garden = 1/0.036

= 27.77 minutes

Rounding off will give us: 28 minutes

So,

Option B is the correct answer ..

Ali, Ben, and Cliff plant seedlings in their neighborhood park. Ali plants 40% of the total number of seedlings, Ben plants 45%
Juli2301 [7.4K]

Answer:

580 seedlings altogether.

Step-by-step explanation:

Given that,

Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. Cliff plants 87 seedlings.

The percentage of the seedling planted by Cliff = 100% - 45% - 40% = 15%

<em>Let x = the total number of seedlings</em>

<em />15\%\ of\ x=87\\\\x=\dfrac{87\times 100}{15}\\\\x=580

Hence, three boys plant 580 seedlings altogether.
