Answer:
41 word/min
Step-by-step explanation:

Answer:
We don't have the statements but I can tell you the following info:
Step-by-step explanation:
83.4/60= $1.39 for each horn
18*1.39= $25.02 for the 18 additional horns.
$83.40+25.02= $108.42 for the total 78 horns
3.5x + 4y = 45
x=6, y= 6 is the most likely answer.
Non whole number variations would be:
x=8, y=4.25
x=4, y=7.75
