Ursula bought five hot dogs at $1.50 each and three salads at $2.50 each. If she had two $10 bills, how much change did she get back?
Five hotdogs cost 5 x $1.50 = $<<5*1.5=7.50>>7.50.
Three salads cost 3 x $2.50 = $<<3*2.5=7.50>>7.50.
The total cost was $7.50 + $7.50 = $<<7.5+7.5=15>>15.
And, Ursula had 2 x $10 = $<<2*10=20>>20.
Therefore, Ursula got a change of $20 - $15 = $<<20-15=5>>5.

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

A man loves to go hiking.  He knows that he has to pack about .5 pounds of supplies for every mile he hikes.  He plans to go for a very long hike.  He knows that he can get 1 resupply during the hike that will be 25% as large as his first pack.  He can hike at a rate of 2.5 mph.  He is going to hike 8 hours a day for 5 days.  How much does he need to bring with his first pack?He is going to hike 8*=40 hours
That means he will be hiking for 40*2.5=<<40*2.5=100>>100 miles
So he needs 100*.5=<<100*.5=50>>50 pounds of supplies
With the resupply he can get up to 1+.25=<<1+.25=1.25>>1.25 times his initial pack
That means his initial pack has to weigh 50/1.25=<<50/1.25=40>>40 pounds

James trains for the Olympics.  He trains twice a day for 4  hours each time for all but 2 days per week.  How many hours does he train a year?He trains 4*2=<<4*2=8>>8 hours per day
He trains 7-2=<<7-2=5>>5 days
So he trains 8*5=<<8*5=40>>40 hour per week
That means he trains 40*52=$<<40*52=2080>>2080
#### 2080[END]

Now, solve this next question in the style of the above examples:

Ursula bought five hot dogs at $1.50 each and three salads at $2.50 each. If she had two $10 bills, how much change did she get back?

### Response:
Five hotdogs cost 5 x $1.50 = $<<5*1.5=7.50>>7.50.
Three salads cost 3 x $2.50 = $<<3*2.5=7.50>>7.50.
The total cost was $7.50 + $7.50 = $<<7.5+7.5=15>>15.
And, Ursula had 2 x $10 = $<<2*10=20>>20.
Therefore, Ursula got a change of $20 - $15 = $<<20-15=5>>5.
