Suppose you charge $4.50/h for baby-sitting. How much will you earn baby-sitting for 3 1/2 hours?

Sergeu [11.5K]

Answer:

You will earn $15.75, $13.50, or $18 depending on how you are getting paid

Step-by-step explanation:

If you are getting paid a flat rate not by the hour, then simply multiply $3.50 by 3.5 to get $15.75

If you are getting paid by the hour, and only by full hours, the you get $3.50 for the first, second, and third hour, but not for the fourth hour because it has only been a half hour, so only $13.50.

If you are getting paid for each hour that you start, then you get $3.50 for four hours, or $18.00 total

Need help with these 3

Tamiku [17]

Answer:

1.) x = 110

$\frac{3}{22} =\frac{15}{x}$

So for 3 to become 15 it would have to be multiplied by 5 because 3 x 5 = 15. And if I multiply the numerator by anything I always have to do the same to the denominator. So I multiply 22 x 5 = x. x = 110

$\frac{3 * 5}{22*5} =\frac{15}{110}$

2.) x = 72

$\frac{x}{16} =\frac{9}{2}$

For 16 to become 2 it has to be divided by 8 because 16 ÷ 8 = 2. And I have to do the same to the numerator of course, so i have to find x ÷ 8 = 9. I know the answer by memory, but for some it's easier to rewrite this as 9 × 8 = x. x=72

$\frac{72}{16} =\frac{9}{2}$
