Answer:
c = 150p + 1000
Step-by-step explanation:
We know the variable cost is 150 per phone, so the total cost will be ...
c = 150p +b . . . . for some value b
We also know the value of c for 8 phones, so we can find b:
2200 = 150(8) + b
2200 -1200 = b = 1000
Then the desired equation is ...
c = 150p + 1000
20 bicycles each of 2 wheels
So 20 x 2 = 40 wheels
10 cars each of 4 wheels
So 10 x 4 = 40 wheels
Total = 40 + 40
= 80 wheels
