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
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.
