N is the number of the Tshirt
c is the cost
the relationship between the cost and the number of the Tshirt is:
12n+3=c
so if 1 is the number of the tshirt so the cost is
12.1+3=12+3=15
if n=2 c=12.2+3=24+3=27
and etc.....

The average of 6 quiz scores, where $x$ is the score of the last quiz, is

$\dfrac{83+81+89+92+80+x}6=\dfrac{425+x}6$

The student needs a minimum average of 86 to earn an A:

$\dfrac{425+x}6=86\implies425+x=516\implies x=91$

so the student needs a score of 91.

Jen picked three fourth in half an hour if she keeps the same rate how many will she pick in 2 hours

Sunny_sXe [5.5K]

Alright, lets get started.

Jen picked three fourth in half an hour.

Half an hour means 30 minutes.

At the same rate, how many she can pick in 2 hours.

2 hours means $2 * 60 = 120$ minutes

Now,

In 30minutes, Jen can pick = $\frac{3}{4}$

In 1 minute, Jen can pick = $\frac{3}{4} *\frac{1}{30}$

In 120 minutes, Jen can pick = $\frac{3}{4} *\frac{1}{30} * 120 = 3$

Hence Jen can pick complete 3 in 2 hours of time.

So the answer is 3 : Answer

Hope it will help :)
