At a concession stand 6 hot dogs cost $6.72. At this rate, how much would 8 hot dogs cost, in dollars and cents?
To find the cost of 8 hot dogs, we can set up a proportion:
6 hot dogs cost $6.72
8 hot dogs cost x
6/8 = $6.72/x
Cross multiplying:
6x = 8 * $6.72
6x = $53.76
Divide by 6:
x = $8.96
Therefore, 8 hot dogs would cost $8.96.
