1. Pedro bought seven dozen candy bars to give out on Halloween night. He gave each trick-or-treater two candy bars. At the end of the night, he had 14 candy bars left. How Many Trick-or-treaters did he have

35

Step-by-step explanation:

First, you need to know 7 dozen, which is 7*12, which equals 84. Altogether, Pedro had 84 candy bars. He had 14 candy bars left over. 84-14=70  He used 70 candy bars. He gave 2 to each trick-or-treater, so do 70/2=35. He had 35 trick-or-treaters.

unless if u could do my questions, if not i wouldn't want to

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
