Karen's students are about to take a standardized test. Karen gets a $500 bonus if their average score is above 75, plus an extra $10 bonus for every additional point the average score increases above 75. So far, Karen has graded 8 tests, and the average is 70. Given that each student can have a maximum score of 150, what combined score do the last two tests need to have for Karen to earn a $600 bonus?
First subtract $500 from Karen's goal bonus amount to find how much she makes from the extra $10/point bonus: $600 - $500 = $<<600-500=100>>100
Then divide the extra bonus by the extra rate: $100 / $10/point = <<100/10=10>>10 points
Then add the 10 extra points to the baseline 75 point goal to find the students' average test score: 10 points + 75 points = <<10+75=85>>85 points
Then added the 8 graded tests to the 2 ungraded tests to find the total number of tests: 2 tests + 8 tests = <<2+8=10>>10 tests
Then multiply the 85 point average by the number of tests to find the total number of points the students need to earn: 85 points/test * 10 tests = 850 points
Then multiply the current average by the current number of graded tests to find how many points have been earned so far: 70 points/test * 8 tests = <<70*8=560>>560 points
Then subtract the number of points earned from the number of points needed to find the combine score the last two tests need: 850 points - 560 points = <<850-560=290>>290 points

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:

Jeff bought 6 pairs of shoes and 4 jerseys for $560. Jerseys cost 1/4 price of one pair of shoes. Find the shoe's price total price.Let X be the shoe price. The jersey's price is 1/4*X.
Jeff bought 6 pairs of shoes and 4 jerseys for 6*X + 4*(1/4X) = $560.
Multiplying through the parentheses produces 6X + X = $560
Combining like terms produces 7X = $560
Dividing both sides by 7 produces X = $80, so the shoe price is $80
Since Jeff bought 6 pairs of shoes, he spent 80*6 = $<<80*6=480>>480 on shoes
#### 480[END]

Tapanga and Corey have 66 candies together. However, Tapanga has 8 more candies than Corey. How many candies does Corey have?Let x = the total number of candies Corey has.
x + 8 = the total number of candies Tapanga has.
The equation for the total number of candies is x + (x + 8) = 66
Combining like terms, we get 2x + 8 = 66
Subtracting 8 from both sides, we get 2x = 58
Dividing both sides by 2, we get x = <<29=29>>29, so Corey has 29 candies.

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

So far, Karen has graded 8 tests, and the average is 70.
