Could you please explain #20,practice test 9,calculator?

Hey

Could you please explain #38 of practice test 9?

I’d be curious to hear what you think is the easiest way to solve Test #9, Section 4 (Calculator), #18. A lot of the students I work with find this challenging because the question says p percent (rather than using p as a decimal).

Thanks!

Hi Mike… can you work through the steps to solve Q 24 from Official Test 9 Section 4? thanks!

Can you explain a more direct way to solve College Board Official Practice Test 9, Math Section 4 #19, than the College Board’s explanation? I seem to remember something about making a chart to solve mixture problems. Would that work here?
