Answer:
Luis incurred 107 extra text messages.
Step-by-step explanation:
Giving the following information:
Luis's cell phone plan costs $39 per month. Text messages cost an additional $0.15 each.
<u>To calculate the number of text messages, we need to use the following formula:</u>
Total cost= 39 + 0.15x
x= number of text messages
55.05= 39 + 0.15x
16.05= 0.15x
107= x
Luis incurred 107 extra text messages.
To square something, you multiply a number by itself.
So the square of 1.1 is

which is equal to 1.21
The equation for interest also works for depreciation
the price drops by 11%
or the price of the machine next year would be 89% of this year
the initial price is 60,000
the amount of years is 5
and the percentage of next year is 89
the full equation would be
60,000(0.89)^5
the price of the machine after five years is <span>33504.356694 (not rounded)
