If your grocery bill came to $205.67 and was reduced to $145.90 after coupons, what is the percent decrease?

Answer 1

Answer: 29.06%

% change=change / original # x 100

(if negative, then the change was positive. If positive, then the change was negative.)

% change = ( $205.67 - $145.90 ) / $205.67 x 100

$59.77 / $205.67 x 100

0.2906 x 100

29.06%

Answer 2

Hello, thank you for taking the time to post your question!

First you want to find the amount of the decrease by taking

205.67 – 145.90 = 59.77

Once you have that you can divide by the total and multiply by 100 to convert it over into a percentage

59.77 / 205.67 x 100% = 29.06%

So the percent decrease in the total price is about 29.06% for this scenario

I hope that helps get you moving in the right direction! Feel free to reach out if you have any additional questions beyond that :)

Answer 3

about 200 to 150 is roughly a 25% discount. 1/4 of 200 is 50 200-50=150

let x=the discount

205.67 - x (205.67) = 145.90 solve for x

205.57x =205.67 - 145.90 = 59.77 divide by 205.67

x= 59.77/205.67= .2906 = 29.1 %

That's about 30% take .3 times 205.57 or about .3 times 206 = 61.8 or 62

subtract that from 206: 206-62= 144 that's very close to 145.90

so we probably did the arithmetic accurately to get a 29.1% discount.

Answer 4

Procent decrease is formula: (145.90 - 205.67)/ 205.67*100% ≅ - 29%.

Minus means that bill decreasing.
