Jenny's volleyball team is hosting a dinner to raise money for new uniforms and equipment. The team's goal is to raise at least $1,100. A dinner ticket costs $20, and guests can also purchase raffle tickets for 50¢ apiece.
If d represents the number of dinner tickets sold and r represents the number of raffle tickets sold, which inequality describes this situation?
a) 20d + 0.5r < or equal to 1,100
b) 20d + 50r > or equal to 1,100
c) 20d +0.5r > or equal to 1,100
d) 20d + 50r < or equal to 1,100
If the team sells 50 dinner tickets, how many raffle tickets does it need to sell?
c) 20d +0.5r > or equal to 1,100
To find the number of raffle tickets needed to sell, we can plug in the values of d and solve for r:
20(50) + 0.5r > or equal to 1,100
1000 + 0.5r > or equal to 1,100
0.5r > or equal to 100
r > or equal to 200
Therefore, the team needs to sell 200 or more raffle tickets.
