If the number of ice cream sandwiches is x

And the number of cookies is y

Then

1.75x + 0.75y = 12.25

and

x + y = 11
y = 11 - x

1.75x + 0.75 (11 - x) = 12.25
1.75x + 8.25 - 0.75x = 12.25
x + 8.25 = 12.25
x = 12.25 - 8.25
x = 4

if x = 4

4 + y = 11
y = 11 - 4
y = 7

x = 4, y = 7

There are 250 votes tallied in a school election with 3 candidate:A, Candidate B, and Candidate C. If 150 of the votes are for c
Tanya [424]

The answer is 75 and here's why.

Let's figure out the amount of remaining votes to prove this.

250 total votes   -    150 votes for candidate a = 100 votes.

                minus ↑ sign

Candidate B received 25% of the votes, so let's find<u> 25% of 100</u>

<u>100 * 0.25 = 25 votes</u>

Candidate B only got 25 votes (that's kinda sad, poor guy)

<u>100 - 25 votes = the # of votes candidate C got </u>

Candidate C got 75 votes!
