Work out the reskuts of these changes. a) a crowd of 8000 people increases by 20%

(b) the price of a $43 000 car decreased by 6%

(c) the mass of a 3.20 kh baby uncreases by 80%​

a is the amount of people went up by 1600 so its 9600

b is it went down by $2580 so the price is now 40420

c so the baby went up by 2.56 kh and now weighs 5.76 kh

Step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

it should be a.

hope it
