The price of gas is $2.15 / gallon today. Last week it was $2.55 for a gallon of gas. What was the percent change in the price?
pickupchik [31]

Answer:

15.69% decrease

Step-by-step explanation:

To find the percent change, we take the original price and subtract the new price

2.55 -2.15 = .40

Divide by the original price

.40/2.55

.156862745

Multiply by 100%

15.6862745 %

Since the price went down, this is a decrease

15.69% decrease

natulia [17]

A blueprint of a house has a scale of 1 in: 6 ft. If a bedroom has a width

of 2 in on the blueprint, what is the actual width of the bedroom?

So 1 inch on the blue print = 6 feet irl (in real life)

So 2 inch on the blue print = 6*2 = 12 feet irl

So the actual width of the bedroom is 12 feet.
