You could buy 135 MP3 songs.
($304.25 - $149 = $155.25 | $155.25 / 1.15 = 135)
Answer:
The answer is c and we'll use c to get the actual answers.
A) n + q = 104
B) .05n + .25q = 22 we'll multiply B) by -4
B) -.2n -1q = -88 then we add A)
A) n + q = 104 which equals
.8n = 16
n = 20 nickels
q = 84 quarters
20 nickels = $1
84 quarters = $21

Step-by-step explanation:
If the boy grows another 5 inches, he will be 1/2 as tall as his sister. HIs sister is 68 inch tall
Let sister = g, and boy = b
2b + 5 = g
g = 68
Plug in 68 for g
2b + 5 = 68
Isolate the b. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
first, subtract 5 from both sdies
2b + 5 (-5) = 68 (-5)
2b = 68 - 5
2b = 63
Isolate the b. Divide 2 from both sides
2b/2 = 63/2
b = 63/2
b = 31.5
The boy is 31.5 inches tall
hope this helps
