John decides to start collecting art.  He pays the same price for his first 3 pieces of art and the total price came to $45,000.  The next piece of art was 50% more expensive than those.  How much did all the art cost?
The first 3 pieces each cost 45000/3=$<<45000/3=15000>>15,000
So the next piece was 15,000*.5=$<<15000*.5=7500>>7,500 more expensive
That means it cost 15,000+7,500=$<<15000+7500=22500>>22,500
That means in total he spent 45,000+22,500=$67,500
#### 67,500
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:

Fifteen more than a quarter of a number is 27. What is the number?A quarter of the number is 27-15=<<27-15=12>>12.
The number is 12*4=<<12*4=48>>48.
#### 48[END]

In today's field day challenge, the 4th graders were competing against the 5th graders.  Each grade had 2 different classes.  The first 4th grade class had 12 girls and 13 boys.  The second 4th grade class had 15 girls and 11 boys.  The first 5th grade class had 9 girls and 13 boys while the second 5th grade class had 10 girls and 11 boys.  In total, how many more boys were competing than girls?When you add up all the girls from all 4 classes, you had 12+15+9+10= <<12+15+9+10=46>>46 girls
When you add up all the boys from all 4 classes, you had 13+11+13+11 = <<13+11+13+11=48>>48 boys
There are 48 boys and 36 girls so 48-46 = 2 more boys
#### 2[END]

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

John decides to start collecting art.  He pays the same price for his first 3 pieces of art and the total price came to $45,000.  The next piece of art was 50% more expensive than those.  How much did all the art cost?

### Response:
The first 3 pieces each cost 45000/3=$<<45000/3=15000>>15,000
So the next piece was 15,000*.5=$<<15000*.5=7500>>7,500 more expensive
That means it cost 15,000+7,500=$<<15000+7500=22500>>22,500
That means in total he spent 45,000+22,500=$67,500
