A survey of 391 children given at a local elementary school showed that 150 like chocolate ice cream 125 like pistachio ice cream, and 166 do not like chocolate or pistachio ice cream. How many children like at most one kind of ice cream mentioned in the survey?

The correct answer is 341 children

Step-by-step explanation:

Firstly you solve for the number of children that like both types of ice cream.

Let us assume it to be x

(150 - x )+ x + (125 - x) + 166 = 391

150 + 125 + 166 - x + x - x = 391

441 - x = 391

X = 441 - 391

X = 50

Since 50 children like at least one type of ice cream, subtracting it from the total no. of children will give the number of children that like at most one type

Therefore, 391 - 50 = 341 children

Alternatively,

Sum up children who like only chocolate ice cream + pistachio ice cream only + does who don't like any type of ice cream

= (150 - 50) + (125 - 50) + 166

= 100 + 75 + 166

= 341 children

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
