Aditi is participating in a walkathon fundraiser. Two anonymous donors agree to donate money according to the distance she walks. The money, A AA, in dollars, that she receives from the first donor for walking d dd kilometers is given by the formula A ( d ) = 12 d A(d)=12dA, left parenthesis, d, right parenthesis, equals, 12, d. The total money, T TT, in dollars, that she receives from both donors for walking d dd kilometers is given by the formula T ( d ) = d 2 + 20 d T(d)=d 2 +20dT, left parenthesis, d, right parenthesis, equals, d, squared, plus, 20, d. Let B BB be the money that Aditi receives from the second donor for walking d dd kilometers. Write a formula for B ( d ) B(d)B, left parenthesis, d, right parenthesis in terms of A ( d ) A(d)A, left parenthesis, d, right parenthesis and T ( d ) T(d)T, left parenthesis, d, right parenthesis.
