We are given the statement that the number of dolls, n is<span> directly as their advertising budget, a, and inversely as the price of each doll, p. In this case, we express it to a formula : n = ka /p where k is the constant of proportionality. applying the law of proportion, 

n1*p1/a1 = n2*p2/a2
</span>12,000*$50/$50,000 = n2* $50 / ($50000 + <span>$65,000)
</span>n2 = 27,600 dolls

Anit [1.1K]

\text{Answer : Number of \$45 shares} =120

\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355
