Part B: $46.50=4.50(9)+6
Marc can buy up to 9 sandwiches ($40.5) plus chips ($6) without going over $50.
To calculate this answer you have to sum up the amount of women and amount of men at the concert: 1493 + 1438 = 2931.
Now you have the total amount of people. To get the precentage of the audience that are men, you do this: 1493/2931. (you divide the amount of men with the amount of every person present).
1493/2931 = 0.5093
you multiply 0.5093 by 100
and you get 50.93%. And that is the final answer.
X=1,y=1
1 )4x+2y=6
2 ) x -y=3
2(x2) ) 2x - 2y=6
Ask a parent to help you with it because I'm not so sure maybe 12/60?
