2. A plumber charges $60 to make a house call and $25 per hour for the time he works to fix the problem. If he works 3 hours, how much does he charge? (Hours worked vs. Charge)

$135 in total.

Step-by-step explanation:

A plumber charges a one-time down payment of $60, and $25 per hour.

He works 3 hours. Multiply his cost per hour with the amount of hours he worked:

3 x 25 = 75

Now, add the number gotten with his one-time payment:

75 + 60 = 135

$135 is how much he charges.

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.  

i can you with this sweetie!
