Answer:
Step-by-step explanation:
Basically, you want to know interest. I = prt is the formula. 'I' will be left blank b/c that's unknown. P is principal, 5000. R is rate, 4%, or 0.04 when turned into a decimal. T is time, 7 years. So now when using the formula, it will all become I = 5000(0.04)(7). What that means is you first multiply 5,000 by 0.04, getting 200. Then when you multiply 200 by 7, it's 1,400, which will leave you with I = 1,400. Interest is 1,400.
Answer:
168 books
Step-by-step explanation:
According to problem, given data are as follows:
Total books for sale = 280 books
Sold on first day = 3 out of 5 books
So, percentage of first day sold = 3 ÷ 5 = 0.6 or 60%
So, we can calculate the total books sold on day one by using following method,
Total books sold on first day = Total books for sale × percentage sold
By putting the value, we get
= 280 books × 60%
= 168 books
