Question

Band students going to a competition can get a special hotel rate of $90 per room. They have a parent donation of $310 to help with the cost.

They have a budget of $2800. Write an equation and use it to find the number of rooms they can purchase.



a
2800=90r+310; 27 rooms
b
3110=90r; 35 rooms
c
3110=90r; 34 rooms
d
2800=90r+310; 28 rooms

Answer 1

C. 3110=90r; 34 rooms

Explanation:

budget: $2800 + donation: $310 = $3110

$3110 ÷ 90 (each room) = 34.5555

so.. they can get 34 rooms with some money left over

Answer 2

it could be C because they have a total cost of 3110 to spend of the 2800 budget plus the 310 donation

90 • 34 is 3060 which is enough and not more than the 3110 like the 35 rooms
