here we are told that
number of dolls sold varies directly with advertising costs
number of dolls varies inversely with price of a doll
so initially
1800 dolls sold when advertising costs were $ 34 000
and price of a doll was $ 25
next they increased the advertising costs to $ 42 000
as we know number of dolls sold varies directly with advertising costs
so here when the advertising costs increase the number of dolls sold too should increases as its directly proportional relationship
we arent told that the price of a doll is changed so there's no effect on the number of dolls sold due to changes in price of a doll
only effect on number of dolls sold is due to increase in advertising costs
increase in advertising cost leads to increase in number of dolls sold
from the given options, only in one option the number of dolls sold are more than 1800 dolls. option is C with 2224 dolls
therefore correct answer is C. 2224 dolls
