The question is first asking us to multiply 28x2, which equals 56. We're going to then round 56 to the nearest ten. The six is greater than five, so we round up,many we're going to round up to 60. So, 60 is your answer.
Alright this equation has two big steps. First we need to find the price after it was marked up, then we need to take that number and find the discounted price.
To find the cost after a percent of it was added, we just need to multiply the two together and add.
=

23.50
+
(
$
23.50
⋅
(
63
%
100
)
)
(we divide by 100 to get the number out of a percent)
=
$
23.50
+
(
$
23.50
⋅
0.63
)
=

23.50
+

14.81
=

38.31
Ok now that we have the number after the price increase, we now need to find the final answer after a discount of
50
%
(do the exact same idea as above but switch the sign)

Answer:
His teacher advised it because he did not have time to tutor Euler privately
Step-by-step explanation:
We know that
Euler in his autobiographical writings, talked about his tutor Johann Bernoulli. He claimed that his tutor was a very busy person who refused to give him private lessons, but gave him many valuable tips to start reading and studying more advanced math books on his own.
therefore
His teacher advised it because he did not have time to tutor Euler privately
