Question

You buy clothing at a sale. You buy sneakers at

2/3 of their original price of $60, a sweater at
7/10 of its original price of $35, and a jacket at
5/6 of its original price of $45. Answer each question and show all your work.

How much money did you spend?
How much money did you save?
What fraction of the total original price did you save?

Answer 1

you spent all together 40.2+24.5+37.8=$102.50.

you saved 19.8+10.5+7.2=$37.50

`(102.50)/(140)`

Explanation:

To find the amount we spend, we multiply the original price by the decimal conversion of each fraction. Then we add the amounts together.

Sneakers cost $60 and you bought them at 2/3=0.6666....

60(0.67)=$40.20 and saved $19.80

Sweater costs $35 and you bought it at 7/10=0.7

35(0.7)=$24.50 and saved $10.50

A jacket costs $45 and you bought it at 5/6=0.8333...

45(0.84)=$37.80 and saved $7.20

We spent all together 40.2+24.5+37.8=$102.50.

We saved 19.8+10.5+7.2=$37.50

We could of spent paying regular price 60+35+45=$140. To find the fraction we place the total we actually paid over the total regular price.
