So there are 15 food booths and 20 game booths. Food booths cost 100 dollars. Game booths cost 50.
100 * 15 = 1500
50 * 20 = 1000
And 5 dollars extra for a day, and 7 dollars extra for a day. Multiply by how many days (d).
7 * d = 7d.
5 * d = 5d.
This means that the expression is:
1500 + 5d + 50 + 7d.
1550 + 12d.
Answer:
23/15
Step-by-step explanation:
2 commercials would take 2×1¾ min= 2×7/4min= 7/2min
so the entertainment segments = 20-7/2= 33/2
each would contain = 33/2÷3 = 33/2×1/3 = 11/2
= 5½
answer =5½
3x - 5y = 11 ⇒ 3x - 5y = 11
1x - 3y = 1 ⇒ <u>3x - 9y = 3 </u>
<u>4y</u> = <u>8</u>
4 4
y = 2
3x - 5(2) = 11
3x - 10 = 11
<u> +10 +10</u>
<u>3x</u> = <u>21</u>
3 3
x = 7
(x, y) = (7, 2)
