The amount he had left plus the two amounts he spent equal the total amount of the check. Add the three amounts together.
$97.75 + $40.20 + $7.40 = $137.95 + $7.40 = $145.35
Isolate the term with
.

Differentiate both sides with respect to
.

By the product and chain rules,

Solve for the partial derivative, then evaluate at
.
