160 has brown hair while

80 do not have brown hair

Step-by-step explanation:

two third means 2/3

therefore to find how many student have brown hair,

we say- 2/3 x 240 = 160

since we know that 160 students have brown hair, we just subtract it from 240

i.e 240 - 160 = 80

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
