A cell phone company offers two different monthly plans.
Plan A costs a flat rate of $0.10 per minute for all calls. Plan B costs $29.99 for
the first 500 minutes and $0.08 for each additional minute. Which plan is less
costly if a person uses 750 minutes per month? Explain.
Answer:
The Best is B = 44.985
Step-by-step explanation:
(A)First thing is that 0.10 times 750 is 75$
(B)but the 29.99 divided buy 500 equal 0.05998.
then you multiplier by 750 which equal 44.985.
this is the best way I hope this helps :)
Estimate the sales tax and final cost of a book that costs $12.95 with a sales tax
of 6%.
Step-by-step explanation:
1.06 × 12.95
13.727
which is 13.73 to find the sales tax subtract it from the original
12.95 - 13.73
which is about 28 cents or 0.28

Write a word problem that could be solved by the equation in problem 8 .
3 1/2 [tex]3 1/2 divided by 7/8= 7/2*8/7= 56/14 =4[/tex]
The word problem is " In a class there are 8 boys and these are 2/3rd parts of total students. How many students are there".
The given expression is 8÷2/3
We need write a word problem which is solved by the above expression.
Word problem : In a class there are 8 boys and these are 2/3rd parts of total students. How many students are there.
Solution
[tex]x[/tex]* × 2/3 =8
Divide both sides by 2/3.
x=8/2/3
x= 8×3 / 2
x= 12
Therefore, the total number of students is 12.
solve for X...........
Answer: First Choice. no solution
Step-by-step explanation:
Given
5 (x + 1) ≤ 5x + 3
Expand parentheses and apply the distributive property
5x + 5 ≤ 5x + 3
Subtract 5x on both sides
5x + 5 - 5x ≤ 5x + 3 - 5x
5 ≤ 3
5 ≤ 3 is not true, therefore, there is no solution.
Hope this helps!! :)

17 students on the math team want to raise 483.62 to buy practice books they have already raised 218.25 if each students raises the same amount how much more money must each student raise
483.62 - 218.25 = 265.37
265.37 / 17 = 15.61
Each student should raise 15.61.
Hope this helps.

Write 4 2/5 as an improper fraction
22/5
Explanation-
First, multiply 4x5, Then you get the product 20. With that 20, add with 2, so, 20+2=22. Now, place denominator as it is, then write 22 as numerator. So you get the answer as 22/5.
Working-
4×5=20
→ 20+2=22
→ 22
→ 22/5

2 = 2.27 - m/4
I am so bad at math, lol! ^^ HELP ME PWEASE!
Answer:
m = 1.08
Step-by-step explanation:
Subtract 2.27 from both sides.2 - 2.27 = -m/4
Simplify 2 - 2.27 to -0.27.-0.27 = -m/4
Multiply both sides by 4-0.27 × 4 = -m
Simplify -0.27 × 4 to -1.08.-1.08 = -m
Multiply both sides by -1 (-m is also known as -1)1.08 =m
Answer:
m = 1.08
Step-by-step explanation:
Basically, we can start off by finding the difference between 2 and 2.27(which is 0.27). Then we can see that 0.27 is equal to m/4. Since 0.27*4=1.08, we can see that m=1.08.
