Answer: 20% lower then A's salary.
Step-by-step explanation:
firstly chain rule is dy/dx = dy/du * du/dx
a) y = 5u² + u - 1 hence dy/du = 10u +1
u = 3x +1 hence du/dx = 3
so dy/dx = 3(10u +1) {sub in u and expand}
b) y= u^-2 hence dy/du = -2u^-3
u=2x+3 hence du/dx = 2
so dy/dx= 2(-2u^-3) {sub in u}
Pennies are small so, if would be more accurate and have whole numbers. If u measured with an inch or meter, u would get a fraction for an answer.
