Ok, so you have the range correct. It is
120<___<150
(It should be less than or equal to, but there's no symbol for that, to my knowledge.)
But the term in the middle shouldn't be .25x
The reason is because that actually quadruples the price in the end, as you seem to have found out. Rather, instead of multiplying x by .25, multiply the numbers in the range by .75.
Here's why:
When you reduce something in price by 25%, you are paying for 75% of the original price. Not 25%. That would be a 75% discount.
So, in all actuality,your answer would be $90
None of those show another way to 64
6*6*6*6=1296
4*4*4*4*4*4=4096
6+6+6+6=24
6*4=24
Another way to show 64 is 8*8 or 4^3
I believe it should be 1.4 since the answer you get is 1.4112903226... you would round but on the tenths place 1.4
