Question

Pls give us model to this question:

Joanne earns $720 a week. She spends 1/3 of her money on groceries and household goods and 3/4 of the remaining money on rent. How much money does she spends on rent, groceries and household goods.

Answer 1

$720 x .333= $239.76
720.00 - $239.76 = 480. 24

$480.24 x .75 ( 3/4 is the same as 75%) = $360.18

Answer 2

Rent = 360
Groceries and hhold goods = 240

Given:
Weekly pay = 720
Groceries and household goods = 1/3 of weekly pay
Rent = 3/4 of money net from groceries.

720 * 1/3 = (720*1)/3 = 240 groceries and household goods
720 - 240 = 480 remaining money for rent
480 * 3/4 = (480*3)/4 = 1440/4 = 360 rental payment
480 - 360 = 120 remaining money.

Joanne spends 360 for rent and 240 for groceries and hhold goods.
