A5cc vial contains 5 grams. you need 250 mg.
how much (volume) will you give?

change mg to g by

therefore to get for 250mg=

More than 26 hours

Step-by-step explanation:

Ava's salary per hour = $12

Bonus for this week = $40

Let the number of hours she works for earning more than $350 be x.

Then, $12x + $40 > $350

=> $12x > $350 - $40

=> $12x > $310

=> x > $310/$12

=> x > 155/6

=> x > 25.8333...

=> x > 26 [rounding to the nearest whole number]

So, she must work more than 26 ours in order to earn more than $350.
