Draw per week = $1,300
Draw for four weeks = 1300 x 4 = $5,200
Four week sales amount = $186,900
6% commission on sales = 0.06 x 186,900 = $11,214
<span>Thus the amount equal to mike’s commission minus the
draw = 11,214 – 5,200 = $6,014</span>
Area of a square = length²
A = x²
16 = x²; x = 4
dA/dx = 2x cm²/s
dx/dt = 6 cm/s
Using chain rule:
dA/dt = dA/dx * dx/dt
dA/dt = 2x * 6
dA/dt = 12x
At x = 4,
dA/dt = 12(4) = 48 cm²/s
646.1 / 34; or write as:
________________________
646.1 <span>÷ 34 ,
</span>______________
= 19.0029411764705882. (Use a scientific calculator; or web-based calculator to get that answer).
