Answer:
5 units were bought
Step-by-step explanation:
Firstly, let us calculate the total amount paid
If what was paid was $9.45, this cost includes the price of the coupon subtracted
Returning the coupon price, we have the total as;
9.45 + 0.5 = $9.95
So to get the number bought, we divide this total by the price for one
We have this as;
9.95/1.99 = 5
Answer:
<u>w^2+9w+20</u>
Step-by-step explanation:
Apply the FOIL METHOD: (a + b) (c + d) = ac + ad + bc + bd
a = 5
b = w
c = w
d = 4
= 5w + 5 x 4 + ww + w x 4
= 5w + 5 x 4 + ww + 4w
Simplify 5w + 5 x 4 + ww + 4w:
<u>w^2 + 9w + 20</u>
