You are saving for a new computer monitor. You already have $75. The monitor costs a total of $400. You save $25 each week. Write an equation using w, to represent the number of weeks that you will have to save in order to purchase the monitor. Use your equation and solve algebraically. Explain your solution. i dont understand pls help

13 weeks

Step-by-step explanation:

1. $400-$75= 325

2. 25w=325 (because you save $25 a week)

3. w=325/25

4. w= 13 (325 divided by 25 is 13)

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

unless if u could do my questions, if not i wouldn't want to
