Delicious77 [7]

Answer:

The sell price of the truck rental after applying the coupon of 20 % is $ 120 .

Step-by-step explanation:

Given as :

The regular rented price for the truck = $ 150

The discount as off coupon = 20 %

Let The sell price for truck after discount = x

<u>So , Discount % = $\dfrac{\textrm market price - \textrm Selling price}{\textrm market price}$ </u>

Or, 20 % = $\dfrac{\textrm 150 - \textrm x}{\textrm 150}$

Or, $\dfrac{x}{150}$ = 1 - $\dfrac{20}{100}$

Or, $\dfrac{x}{150}$ = $\dfrac{100 - 20}{100}$

or, $\dfrac{x}{150}$ = $\dfrac{80}{100}$

∴ x = $\frac{80\times 150}{100}$

I.e x = 8 × 15

Or, x = 120

Hence the sell price of the truck rental after applying the coupon of 20 % is $ 120 . Answer

Help please.<br> Is algebra.

yKpoI14uk [10]

Answer:

Step-by-step explanation:

To find the average rate of change, we can use the formula: (y2-y1) / (x2-x1).

Let (15, 45) be (x1, y1) and (29, 87) be (x2, y2).

So we have: (87-45) / (29-15)

This can be simplified to: 42/14, or 3.

Let me know if this helps!
