Answer:
You pay $38.25 after the discount is applied
Step-by-step explanation:
First take 15% of 45 by multiplying 45 by 0.15 (which is 15% as a decimal)
0.15 * 45 = 6.75
Subtract 6.75 from $45 and then you get $38.25!

Answer:
BC = 96
Step-by-step explanation:
Since AD is an altitude, then ∠ ADC = 90° , thus
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
Thus
BC = BD + DC
= 2x + 3x - 4
= 5x - 4
= 5(20) - 4 = 100 - 4 = 96
Eighty-one thousand two hundred seventy-one.
