Question

You are buying party favors that cost $2.47 each. You can spend no more than $30 on the party favors. What domain and range are reasonable for this situation?

Answer 1

domain = number of party favors you buy
range= price you pay for total party favors

Find the max number of party favors you can buy
20 = x * 2.47
x = 12.15, so you can only afford 12.
That means that domain is from 0 to 12
and the range is from 0 to 12*2.47, or 0 to $29.64
