the change in the scale factor is  \frac{45}{40} .Correct option C) StartFraction 45 feet over 40 feet EndFraction

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

Here we have , Norma Ann planned a rectangular courtyard, as shown in the scale drawing below. A rectangle with length of 15 inches and width of 5 inches. She decides to change the width, the shorter side of the courtyard, from 45 ft to 40 ft. We need to find Which expression finds the change in the scale factor . Let's find out:

Initially the ratio of width to actual width is :

⇒ \frac{5}{45}

Now , After 45 ft is changed to 40 ft , New ratio becomes :

⇒ \frac{5}{40}

So , change in scale factor is from  \frac{5}{45} to  \frac{5}{40} i.e.

⇒ \frac{\frac{5}{40} }{\frac{5}{45} }

⇒ \frac{5}{40}(\frac{45}{5} )

⇒ \frac{45}{40}

Therefore , the change in the scale factor is  \frac{45}{40} .Correct option C) StartFraction 45 feet over 40 feet EndFraction

Given that, Linda's start up cost for her online jewelery store was $250

She has to pay an additional $60 per month to keep it running

To find: Equation that models this situation

From given,

Start up cost = $ 250

Let "x" be the number of months she keeps the store running

Additional pay per month = $ 60

Thus, the total cost Linda spend to keep the store running is given as:

Total Cost = Startup cost + (Additional pay per month)(number of months)

Total\ Cost = 250 + 60x

Thus the equation that models the given situation is found
