Answer:11.7
Step-by-step explanation:
1. Recognize variables. Starting price is 9, it’s increasing by 1.5% each year, the question asks for the price in 20 years.
2. Convert percentage to decimal. Most calculators won’t understand multiplying by percentages, and instead will understand multiplying by decimals. A decimal is something we can easily work with. It is more commonly taught to work with decimals as well. With that said 1.5% equals .015. (The number in the ones place in the percentage is always in the hundredths place when converted to a decimal, the tens to the tenths, the hundreds in the percentage to the ones place in the decimal, the hundredths in the percentage to the ten thousandths in the decimal. Basically, every individual number [the 5 in 1.5] moves two spaces to the right when going from percentage to decimal form, likewise two to the left going from decimal to percentage form. 23%=.23, 104%=1.04, 0.5%=.05, 1.234%=.01234)
3. Make your equation
20(9*(.015))+9
+9 is your starting point
9*(.015) gives you the amount the price increases per year
20 is multiplied then to that increased price for the next 20 years
4. Crunch em numbers
PEMDAS
You are multiplying the weight lost each week and the number of weeks elapsed. This means that the result is the total weight that Evie has lost.
There are 16 cups in a gallon therefore 5/16 is the fraction
Answer:
loss by $960
Step-by-step explanation:
The purchase price of the car = $6000 ----------(A)
The percentage increment = 40%
Hence increment = 40% of $6000
= 0.40 x $6000
=$2400
Hence New Selling price for the lady = $6000+$2400= $8400
now as she was unable to sell the ca at this price. The price was educed by 40%
Hence reduced price = 40% of new selling price
=40% of $8400
=0.40 x $8400
=$3360
Hence Final Selling price = $8400 - $3360
= $5040 -----------(B)
Since
(A) > (B)
Purchase price is bigger than the final sold price
Thee will be loss by $6000-$5040= $960
