The clothes weigh 14.77 kilograms.

Given:
Weight of suitcase = 50 pounds
Towels = 20% of weight
Shoes = 15% of weight
Clothes = 65% of weight

convert pounds to kilograms using proportion:

<u>pounds</u>        <u>2.2</u> = <u>50</u>
kilograms       1           x

2.2x = 50 ⇒ x = 50/2.2 ⇒ x = 22.73 kgs

Clothes : 22.73 kgs * 65% = 14.77 kgs
Towels  : 22.73 kgs * 20% =   4.55 kgs
Shoes   : 22.73 kgs * 15% =   3.41 kgs

Maxie spent 15 hours doing her homework last week this week she spent 18 hours doing her homework she says that she spent 120% m
scZoUnD [109]

Answer: She's wrong.

Step-by-step explanation:

Numbers of hours used in solving homework last week = 15

Numbers of hours used in solving homework this week = 18

Percentage increase = (18 - 15) / 15 × 100

= 3/15 × 100

= 1/5 × 100

= 20%

Since Maxie said that she spent 120% more time doing homework this week, she's wrong. She only spent 20% more.
