Question

Help plsssssssssssssssss​

Answer 1

Answer:

1) 75 copies were sold

2)expected wage=720

Step-by-step explanation:

in this equation, y represents wages and x represents number of copies sold

lets take the trendline, y=6x+120

since the amount earnt is $570, we can take this to be our y variable

570=6x+120

450=6x

x=75

1) 75 copies r sold

2) this time we substitue the 100 for x

y=6(100)+120

y=600+120

y=720

2) expected wage=720
