Answer: $7.24
Step-by-step explanation:
Facts:
Cost of a ticket in 2000: $5.39
Cost of a ticket in 2004: $6.21
Cost of ticket in 2009: ?
Step 1: Find the unit rate (how much the cost of a ticket goes up every year)
Okay so in the span of 4 years (2000-2004), the price went from $5.39 up to $6.21. The first thing to do is find out how much the price went up in 4 years.
6.21-5.39= 0.82
The cost went up by $0.82, or 82 cents, in 4 years. How much did it go up every year? To answer this question, divide this $0.82 into 4 years:
0.82÷4= $0.205 per year (not rounding this number until the end will make the result more accurate)
Step 2: Multiply by 9 to find the cost of a ticket in 2009
The first thing to do is find out how much the cost of a ticket increarsed in 9 years:
0.205x9= 1.84500
1.84500---> 1.845---> about $1.85
Next, add that to the cost of a ticket in 2000, because that was the starting cost.
5.39+ 1.85= $7.24
Hope this helps :)) Also brainliest would be appreciated
