A car originally costs $20,000. Its price went up by 20% and then by another $8,000. How much did the price go up as a percentag
Nataliya [291]

Answer:

60%

Step-by-step explanation:

20,000

we can move the decimal place one to the left to find 10 percent

2,000

multiply 10 x 2 to find twenty percent or 4,000

we add this to the original total. 24,000

then add the 8,000

32,000

we know find one percent of the original total

200

and find the difference between the two totals

32000-20000 = 12,000

12000 divided by 200 which is 6

multiply six by ten to get

60 percent

35/8 simplified? Explain
iVinArrow [24]
<span>You are given 35/8. You are asked to reduce it into the simplest form. You have to find the greatest common factor of 35 and 8. First, divide 35 by 5 we get 7. Divide 8 by 5 gives a fraction. If we try to divide it by a larger number such as 35 divided by 35 equals one. And 8 by 35 gives a fraction. If we would not try to divide each of them, 35 and 8, to any number, the number stays the same. Therefore the simplest form of 35/8 is 35/8.</span>
