How do I work this out: beth took a math test and scored a 75. She took another math test and scored 20% higher. Whatis her scorefor the second test?
75 * 1.20 = 90
To find Beth's score on the second math test, you need to calculate 20% of her score on the first math test and add it to her original score.
Here's how you can work it out step by step:
Step 1: Calculate 20% of her score on the first math test.
- To find 20% of a number, multiply the number by 0.2. In this case, Beth's score on the first math test is 75.
- So, 20% of 75 can be calculated as: 75 * 0.2 = 15.
Step 2: Add the calculated value (20% of her score on the first math test) to her original score.
- Beth's score on the first math test is 75.
- Add the value calculated in Step 1 to her original score: 75 + 15 = 90.
Therefore, Beth's score for the second math test is 90.
