A store is going out of business. Everything is marked down 40%. How much do you pay now for an item that used to cost $150? Explain how you got your answer.

You would pay $90 now for an item that used to cost $150.

Step-by-step explanation:

Here's how I thought of it. There are two ways to solve this problem.

Because we know that the item is discounted by 40%, that leaves 60% of its price left. (100% price - 40% price = 60% price).

Thus, you would multiply $150 by 0.6 (or, 60% in decimal form), which equals $90.

Alternatively, you could also multiply $150 by 0.4 and just subtract what you get from the total. That number is 60, and $150 - $60 = $90.

Use whichever way makes more sense to you!

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
