2005 CEMC Gauss (Grade 7) Problems/Problem 7

Problem

Karen has just been chosen the new “Math Idol”. A total of $1,480,000$ votes were cast and Karen received $83\%$ of them. How many people voted for her?

$\text{(A)}\ 830,000 \qquad \text{(B)}\ 1,228,400 \qquad \text{(C)}\ 1,100,000 \qquad \text{(D)}\ 251,600 \qquad \text{(E)}\ 1,783,132$

Solution

Since $83\%$ in decimal form is $0.83$ , then the number of people who voted for Karen is equal to $0.83\times 1,480,000 = 1,228,400$ . The answer is $B$ .
