Acell phone company charges a basic rate of $19.99 per month for 300 minutes of local usage. any local usage over 300 minutes is charged at $.10 per minute. all long distance calls are charged at $.25 per minute. write and simplify an expression that gives the total monthly bill if x is the number of local minutes and y is the number of long distance minutes. evaluate the expression if local usage totals 375 minutes and long distance usage totals 54 minutes.

total = 19.99 + 0.10(x-300) + 0.25y

x = 375

y=54

total = 19.99 +0.10(375-300) +0.25(54)

total = 19.99 + 0.10(75) + 0.25(54)

total = 19.99 + 7.50 + 13.50

total = $40.99

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
