Joaquin has a grade of 81 and 70 on her first two algebra test if she wants an average of 73 what possible score can she get on
her last test
1 answer:
81 + 70 + x = 3(73)
first multiply 3(73)
81 + 70 + x = 219
combine like terms
151 + x = 219
subtract 151 from both sides
x = 68
Joaquin needs to score a 68 on her next test to maintain an average of 73.
