The number of dolls sold when the advertising is increased to $42,000 is going to be 2,224. The correct answer is C.

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
