Question

Alyssa took a math test with 2o questions and answered 16 questions correctly in order to get an a she needs to answer at least 90% of the questions correctly did Alyssa make an a

Answer 1

Answer:

Step-by-step explanation:

How many questions is 90% of 20?  That's the question we need to answer.  Algebraically, the equation looks like this:

x = .90(20) so

x = 18

If she only answered 16 correctly, she did not get the A.  She needed to answer 18 correctly, because 18 is 90% of 20.

Answer 2

Answer:

No, she did not make an A.

Step-by-step explanation:

She answered 16 questions correctly out of 20.

To find a percent, divide the part by the whole and multiply by 100.

part = 16

whole = 20

percent = part/whole * 100 = 16/20 * 100 = 80

She got 80%.

To get an A she needs 90%, so she did not make an A.
