Answer: BC = 5.83
Step-by-step explanation:
Luckily, the triangle is placed on the graph nicely so we can count the legs of the triangle:
AB = 5
AC = 3
BC = ?
To find BC, we can simply use the Pythagorean Theorem:
5^2 + 3^2 = c^2
25 + 9 = c^2
34 = c^2
Now square root to find c, or BC.
c = 5.83 (rounded by nearest hundredth)
the coupon is 35% off, therefore, she actually paid 65%
0.65(128.25) = 83.36 (what she paid without tax)
now we add the sales tax of 4%
83.36 (1.04) = 86.69 <== total cost
