So, 4 x 3 is 12, so 4 blades cost 79.74 x 3 (because every turbine has 3 blades each) is 318.96
Let x be the total weekly sales.
His salary is $300/week + 1.8% (x), if he wants to earn $570, then:
300 + 1.8%(x) = 570
1.8%(x) = 270
0.018 (x) = 270
and x = 270/0.018 = $15,000
Calculate least common factor of 12, 15 & 18.
It will be 180.
answer is
<span>B. 150 < N < 200</span>
I think it’s D sorry if I’m wrong
