Jake isn't doing well in history.  He made a 67 on his first test. His second test was even worse; he scored a 52. What does Jake need to score on the next test to have a test average of 70?

thanks for any help!

70*3=210

67+52=119

210-119=91

he needs a 91 on his next test

67 + 52 + x = 210

x = 91

$\frac{67 + 52 + x}{3} = 70$

$119 + x = 210$

$x = 210 - 119$

$\boxed{x = 91}$
