Hi Mike, Can you please explain Question 11, Test 6, section 3 ? I know the parabola opens downward, but I’m confused after that. Thanks.

Test 6 Section 3 #13

Hi. Please, can you explain test 6,section 3,number 14. I get confused by “at least twice as many containers of detergents as many softeners.” I was thinking it was 2d< or = s. Please explain why it is not so. Thanks

How do you do #18 in Test 6 Section 3 without a calculator?

Practice Test 6, number 17, no calc.

Can you do Test 6 Section 3 #15?

Test 6 #20 from the no calculator section

I’m not sure you are answering questions about Practice Test 6 yet. If so, would you please work # 12 in section 3 of that test?
