Answer:

Step-by-step explanation:

Distance between Miami and Naples = 107 miles

Distance between Miami and Jacksonville is about three times this distance.

Distance between Miami and Jacksonville = 3 * 107 miles

= 321 miles

Landon estimates the distance between Miami and Jacksonville is about 400 miles

The estimate is too high

He should have estimated 107 miles to 110 miles which gives a total of 330 miles

Estimated 400 miles compared to 330 miles is too high

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.

Martin is interested in joining a gym and has researched the cost of two gyms close to his
pochemuha

Answer:

I suppose that you want to find which gym will be cheaper for you.

We have two equations:

• Gym A: 30m + 50

• Gym B: 10m + 100

First, let's find the value of m such that both gyms cost exactly the same:

30*m + 50 = 10*m + 100

Let's solve this for m

30*m - 10*m = 100 - 50

20*m = 50

m = 50/20 = 2.5

now:

for m < 2.5, Gym A will be cheaper, because the y-intercept is smaller.

for m > 2.5, Gym B will be cheaper, because the slope is smaller,

Then depending on the number of months that Martin wants to go to the gym, he can se the info above to pick the one that is cheaper.
