To find the score you need on your last test to achieve a total of 340 points, we first need to calculate the total points you currently have from your first three tests.
Your current scores are:
- Test 1: 70
- Test 2: 80
- Test 3: 90
Now, let's sum these scores:
\[
70 + 80 + 90 = 240
\]
Now, you want a total score of 340 points. Let \( x \) be the score you need on your last test. We can set up the equation:
\[
240 + x = 340
\]
To isolate \( x \), subtract 240 from both sides:
\[
x = 340 - 240
\]
\[
x = 100
\]
Therefore, you need to score **100** on your last test to reach a total of 340 points.
