<span>Let the price (before tax) be x.
The tax is 7% of x, so it is 0.07x.
The price plus the tax add up to $45.
x + 0.07x = 45</span>
Dy/dx (2x⁵ y³ - 4y/x)
dy/dx (2y³ x⁵ - 4y/x)
dy/dx ( 2y³ x⁵ ) - dy/dx (4y/x)
= 2y³ 5x⁴ - (-4y × 1/x²)
=
10x⁶ y³ + 4y

Let's use the variable r to represent ricky's base hits:
Ricky is r
Pedro is r + 276
So:
r + r + 276 = 2676
2r = 2400
r= 1200
Ricky hit 1200 base hits, and Pedro hit 1476 base hits.
