Question

The high school marching band is raising funds to travel to a national competition. The band needs to raise at least $4800 for their travel. The band is hoisting a spaghetti dinner and is selling tickets for $12 each. The band also has to buy all the food for the dinner at a cost of $625. What is the least number of tickets that need to be sold for the band to have enough money for their travel?

A. 347 tickets
B. 348 tickets
C. 452 tickets
D. 453 tickets

Answer 1

D) 453

Explanation:

let 'd' = number of dinners that much be sold

we can set up this inequality:

12d - 625 ≥ 4800

add 625 to each side to get:

12d ≥ 5425

d ≥ 5425/12

d ≥ 452.08

we have to round up because you need a whole number to represent a ticket

Answer 2

c

Explanation:

452x12=5424 aand 4800+625=5424
