First change 80% to a decimal
80% = 80/100 = 0.80
Next, multiply 35 with 0.80
35 x 0.80 = 28
Next, subtract the number gotten (28) with the regular price (35)
35 - 28 = 7

$7 is the sales price

Answer:
a) 62%
b) 44%
Step-by-step explanation:
Beforehand we have the information that the amount of shoppers, let`s call it n= 150.
To answer the first question, we need to know the amount of shoppers that do not possess an email account: this is the sum= 18`+75 (both the shoppers without and with access to a computer at home buth without an email). Lets call it a.
The percentage is defined by:
%of shoppers that dont have and email account= a/n*100= (18+75)*100/150= 62%
The next question is the percentage of shoppers with computer access at home, thus the sum of 48+18, both who have and dont have an email account but the have computer access at home. Lets call it b.
So
%of shoppers that have computer access at home = b/n*100= (48+18)*100/150= 44%
