6. Tony is going to buy a new bike. The bike costs $120.50. If Tony uses a 25% coupon how much will he pay for the bike after using the coupon? (10 pts)

$90.38

Step-by-step explanation:

25% of $120.50 is $30.125

$120.50 - $30.125 = $90.375 rounded to $90.38

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
