What value of m will make this expression equal to 0?
5(m +2.25)
2.5
-7.25
-2.25
0.25
2.25

-2.25

Step-by-step explanation:

The only way the expression can equal zero is if the numerator is zero.

The numerator is the product of 5 and the expression m + 2.25

A product is equal to zero if one of the factors equals zero.

5 is obviously not equal to zero, so the only way the product of 5 and m + 2.25 can equal zero is if the factor m + 2.25 equals zero.

We set m + 2.25 equal to zero and solve for m.

m + 2.25 = 0

Subtract 2.25 from both sides.

m = -2.25

If you add -2.25 to 2.25, you get zero. Zero times 5 equals zero. That meakes the expression equal to zero.

-2.25

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
