She needs 5 cups of flour and 3 cups of sugar.
Answer:
2,000
Step-by-step explanation:
write out an equation that represents the problem. the original price X fell by 15% to a new price of 1700:
X - (X*15%) = 1700
X(1-0.15) =1700
X=1700/(1-0.15)
X=2,000
convert 15% to decimal form:
15%=0.15
Put it into standard form so you would have
27x10¯6 divided by 9x10¯6
Then you can divide the numbers so 27/9 = 3
Then to divide the powers you just take them away so - 6--6 = - 6 +6 = 0
Therefore the answer is just 3
