Answer: $230
Step-by-step explanation:
Since the discount Eric got was 75% of the normal price, you would divide 172.50 by 0.75 and you would end up getting the original price, or $230.
B.
sin^2x + cos^2x =1
hence Sin^2x-1 = - cos^2x
3 7/8 Converted into decimal equals 3.875
7/8 = 0.875 + 3
Given a variable, x, the compound ineaquality representing the range from a to b inclusive of the variable is given by

where a is the least value and b is the greatest value.
Thus, given a variable f, representing the frequencies for the three octaves of a <span>typical acoustic guitar.

Where the range of the frequencies is between 82.4 Hertz and 659.2 Hertz inclusive.
The complex inequality, representing <span>the range of frequencies for a guitar tuned to "concert pitch"</span> is given by
