William has 15 3/5 quarts of paint. He equally divided the paint into 3 gallon-sized

Vikki [24]

Answer:

He has left 1.3 gallons of paint

Step-by-step explanation:

* Lets explain how to solve the problem

- William has 15 3/5 quarts of paint

- He divided the amount of paint equally into 3 gallon-sized containers

- He used 2 containers

- We need to find how many gallons of paint is left

* Lets use the information above to solve the problem

∵ William has 15 3/5 quarts of paint

∵ 15 3/5 = 15.6 quarts as a decimal

∵ 4 quarts = 1 gallon

∴ 15.6 quarts = 15.6 ÷ 4 = 3.9 gallons

∵ He divided the paint equally into 3 gallon-sized containers

∴ Each container has = 3.9 ÷ 3 = 1.3 gallons

∴ Each container has 1.3 gallons of paint

∵ He used 2 of them

∴ He used ⇒ 2 × 1.3 = 2.6 gallons

∴ The third container is left

∵ The container has 1.3 gallons

∴ He has left 1.3 gallons of paint

What is 60% of $49000?

katen-ka-za [31]

Suppose you have a Kohls coupon of $49000 and you want to know how much you will save for an item if the discount is 60 percent.

Solution:

Replacing the given values in formula (a) we have:

Amount Saved = Original Price x Discount in Percent / 100. So,

Amount Saved = 49000 x 60 / 100

Amount Saved = 2940000 / 100

Amount Saved = $29400 (answer).

In other words, a 60% discount for a item with original price of $49000 is equal to $29400 (Amount Saved).

Note that to find the amount saved, just multiply it by the percentage and divide by 100.
