Sofia can type the work in 10 hours. Nova can do it in 15 hours. They work together for 4 hours, then Sofia and Nova finish the
AlladinOne [14]

Answer:

2 days.

Step-by-step explanation:

Let, Sofia can type the x amount of work in 10 hours.

So, in one hour Sofia can type \frac{x}{10} amount of work.

Again, Nova can type x amount of work in 15 hours.

So, in one hour Nova can type \frac{x}{15} amount of work.

Hence, if they work together, they can type \frac{x}{10} + \frac{x}{15} = \frac{6x + 4x}{60} = \frac{10x}{60} = \frac{x}{6} amount of work in one hour.

Therefore, working together they can type the x amount of work in \frac{x}{\frac{x}{6} } = 6 days.

So, they have to work for (6 - 4) = 2 days more to finish the work. (Answer)

You are the senior class president, and you are selling items for a school fundraiser. You have cell phone cases and t-shirts th
bogdanovich [222]

Assume every item you sold was a case.

You would've gotten : 48 x 10 = $480.

But in reality, you only got $350, so it's a $130 difference.

Replace 1 cell phone case with 1 t-shirt -> the difference go down 5 every time. (for example, if you sold 47 case and 1 t-shirt, the difference go from $130 to $125)

So, the amount of t-shirt you sold was 130 : 5 = 26 (t-shirts)

And, you sold : (350 - 26 x 5) : 10 = 22 (cases)


Recheck : 26 + 22 = 48 items, and 26 x 5 + 22 x 10 = 130 + 220 = 350.
