Shirley is going to have the exterior of her home painted tim’s painting charges $250 plus $14 per hour colorful pens charges $22 per hour how many hours would the job need to take for tim’s painting to be the better deal

It takes 32 hours for Tim’s painting to be better deal.

SOLUTION:

Given, Shirley is going to have the exterior of her home painted  

Tim’s painting charges plus per hour  

Colorful pens charges per hour  

We have to find required hours for Tim’s painting to be the better deal . Let the number hours be h.  So, Tim’s charges = colorful pens charges  

Now, Let us check charges after 32 hours.

So, at 31 hours colorful pens are economical but at 32 hours Tim painting is economical.

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2
