Question

Last week, the price of oranges at the farmers market was $1.75 per pound. This week, the price has decreased by 20%. What is the price of oranges this week?

Answer 1

Answer:

$\ 1.40$

Step-by-step explanation:

We can calculate it through some ways. Firstly writing as an equation, just to organize it:

1.) $P=1.75-(\frac{20}{100} *1.75)\Rightarrow P= 1.75 -(0.2*1.75) \Rightarrow P=1.75-(0.35) \Rightarrow P=\ 1.4$

2) Dividing 1.75 by 1.20. Because it is 20% we add to 1, and then divide it.

$1.75 : 1.2 \approx 1.4 =\ 1.40$

Answer 2

The price of orange this week is $1.40

Let x represent the price of the orange after the decrease.

Since the price of the orange presently is $1.75 per pound. The decreased price is given by:

Amount of decrease = 20% of original price

Amount of decrease = 0.2 × $1.75

Amount of decrease = $0.35

Therefore the price of orange this week (x) is:

x = $1.75 - $0.35

x = $1.40

Therefore the price of orange this week is $1.40
