For his phone service, alonzo pays a monthly fee of
$18
, and he pays an additional
$0.05
per minute of use. the least he has been charged in a month is
$75.95
.
what are the possible numbers of minutes he has used his phone in a month?
use
m
for the number of minutes, and solve your inequality for
m

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
