If you have to pay full price for the first bag then there is no discount off the first bag purchased for 10 dollars. If you get 50% off on the second bag then the second bag will cost you five dollars. So that mean you would have to pay 15 dollars for both bags instead of 20 dollars. So your discount on the entire purchase of two bags would be 25% of that purchase.

Answer:b
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
From the table, we know at least 2 ordered pairs. We can use the slope formula on any 2 ordered pairs on the table to get 3.
As the sum of two complementary angles = a + b = 90
degree -------(1)
Difference of two complementary angles = a – b
According to question;
The difference of two complementary angles exceed the
sume (90) by 86.
So
a – b = 90 – 86 = 4 -------(2)
adding equation (1) and (2);
2a = 90 + 4 = 94
a = 94 / 2 = 47
putting a = 47 in equation (1);
47 + b = 90
b = 90 – 47 = 43
<span>
So angle a = 47 and
angle b = 43</span>
