Answer:Julia's Grade is 70%, and the items she got wrong if she scored 85% in the test would be 3 items. Step-by-step explanation:Julia got 14 out of 20 items correct, so:Grade (%) = (14/20) × 100 = 70% Julia's Grade is 70%.Now, if she got 85% on the test, we can calculate how many items she got correct first by using the percentage:Correct Items = (85/100) x 20 = 17Since she answered 17 items correctly, the number of wrong answers is:Wrong Items = 20 - 17 = 3So, Julia got 3 items wrong when she scored 85%.
