(x+5)3
(x+5) · 3
3(x+5)
3x+ 3 · 5
3x + 15
Two ways:

=

and 1/4 = 25%
Another way.
300 = n% of 1200
Problem - we can't move n% back two place to change it to a decimal since we don't know what n is. Solution - move the decimal back on the 1200 two places because since of means x, it doesn't matter. Sample .45 x 32 = 45 x .32 Notice that the decimal can be place on either number and it results in the same answer.
So 300 = 12n (1200 moved back 2 places)
now divide by 12
<u>300</u> = <u>12n
</u>12 12 and once again n=25(%)<u>

<span>If you used the phone 130 minutes from 6 am to 7 pm, that would cost $13.00. 400 minutes from 7 pm to 6 am at a 10% discount would cost you $36.00. Add totals to get $49.00. Tax at 6% is 2.94. Your total bill would be $51.94.
Total bill = (0.10+0.06) x 130 + (0.10+0.06) x 400 x 0.90
= $ 51.94</span>
