While at the music store, drew bought 5 cds, all at the same price. the tax on his purchase was $6 and the total was $61. write and solve an equation to determine the price of each cd

The price per CD that Drew bought=$11

Step-by-step explanation:

Margie's total cost can be expressed as;

C=(p×n)+t

where;

C=total cost

p=price per unit of CD

n=number of CD bought

t=tax on purchase

In our case;

C=$61

p=unknown

n=5

t=$6

replacing;

61=(5×p)+6

5 p+6=61

5 p=61-6

5 p=55

p=55/5

p=11

The price per CD that Drew bought=$11

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

the 3rd on is correct
