Answer:
approximately 15%
Step-by-step explanation:
What we know:
Sarah wants to raise her math grade to a 98.
Her grade is currently an 85 in math.
Subtract 85 from 98, and put the difference over 85.
(98-85)/85
13/85
Does it need to be simplified? 13 is prime so no.
13/85 equals (rounded to nearest 10,000th) 15.2941%, so Sarah must raise her grade by approximately 15% to improve her math scholarship chances.
