Your favorite craft store had a weekend sale. On the first day, all $10 items were 70% off. You bought some number of these of t
Svet_ta [14]
For the first day we have the following function:
 f (n) = (0.3 * 10) n + 8
 For the second day we have the following function:
 f (n) = (0.4 * 10) n + 5
 You spent the same amount of money as the day before:
 (0.3 * 10) n + 8 = (0.4 * 10) n + 5
 3n + 8 = 4n + 5
 n = 8-5
 n = 3 items
 We evaluate each function for n = 3
 f (3) = (0.3 * 10) * 3 + 8 = 17 $
 f (3) = (0.4 * 10) * 3 + 5 = 17 $
 The total amount of money is:
 17 + 17 = 34 $
 Answer:
 
you purchase 6 items
 
you spend at the craft store during the sale $ 34

The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h. A=h ( a+b ) 2 Solve for b.
Lelu [443]
I believe the right equation for determining the area of a trapezoid is as below,
     A = h(a + b)/2

To determine the expression for b which is the length of one of its bases, we multiply the equation by 2.
    
    2A = h(a + b)

Then, divide both sides of the equation by h,

    2A/h = a + b

Then, subtract a from both sides of the equation,
    2A/h - a = b

Lastly, interchange the sides of the equation to reveal the answer.
<em>     </em>
<em>   b = 2A/h - a </em>
