Answer:
$260.24
Step-by-step explanation:
To find how much Irene will save from buying from the lower-priced company, let's first compute for how much both companies are offering.
Verizon offers 15/10/5 chain discount.
The total discounted price that Verizon offers can be solved by getting complement of the percentages and convert them into their decimal equivalence and multiplying them.
15% = 85% or 0.85
10% = 90% or 0.90
5% = 95% or 0.95
Now we multiply them together.
Total Paying Price Rate = (0.85)(0.90)(0.95)
Total Paying Price Rate= 0.72675 or 72.68%
Now to get how much the discount really is we subtract the Total Paying Price by 100%.
Total Discount = 100% - 72.68%
Total Discount = 27.32%
Now since Irene is buying 10 phones we multiply the original price by 10.
Total Original Price = 95.24 x 10 = $952.4
Then we simply multiply the total original price by the Total paying price rate.
Overall = 952.4 x 0.72675
Overall = $692.16
So the overall price that Irene will pay in Verizon is $692.16
Now let's solve for the Cellular company.
Cellular Company offer 25/5 chain discount
25% = 75%
5% = 95%
Now we do the same as the Verizon one.
Total Paying Price Rate = (0.75)(0.95)
Total Paying Price Rate = 0.7125 or 71.25%
Then we solve for the discount.
Total Discount = 100% - 71.25%
Total Discount = 28.75%
Now for the price of 10 phones.
Total Original Price = 98.49 x 10 = $984.9
Overall = 984.9 x 0.7125
Overall = $701.41
So the overall price for the Cellular Company is $701.41
So the lowered price company is Verizon.
If Irene buys the phones from Verizon, she will save $260.24.
