A survey of 391 children given at a local elementary school showed that 150 like chocolate ice cream 125 like pistachio ice crea

creativ13 [48]

Answer: 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

The value (in cents) of the change in a purse that contains twice as many nickels as pennies, five more dimes than nickels, and

nexus9112 [7]

Value of the pursue in cents: $131p+175$

Step-by-step explanation:

Let's call:

$p$ = number of pennies

The problem tells us that the pursue contains twice as many nickels as pennies, so the number of nickels is

$n=2p$

Also, the pursue contains five more dimes than nickels, so the number of dimes is

$d=n+5=2p+5$

And finally, the pursue contains as many quarters as dimes and nickels combained, so the number of quarters is

$q=d+n=(2p+5)+2p=4p+5$

The value of each type of coin is:

Penny: 1 cent

Nickel: 5 cents

Dime: 10 cents

Quarter: 25 cents

So, the total value of the pursue in cents is:

$1p+5n+10d+25q$

And substituting,

$=p+5(2p)+10(2p+5)+25(4p+5)=\\p+10p+20p+50+100p+125=\\131p+175$

So, this is the value of the change in the pursue in cents.
