Answer:
it costs $2.80 per padlock
Step-by-step explanation:
Okay since we know how much it costs to buy 9 padlocks, we can deduce that there has to be a unit rate for each padlock so we divide the cost of the 9 padlocks by the number of padlocks to find the unit rate:
25.20/9= 2.8
Now we convert the answer into money like so:
2.8 = 2.80 = $2.80
So it costs $2.80 for each padlock
