joanne kearns 720
pounds a week .she spends 1/3 of her money on rent and 3/4 of the remaining on groceries .how much money does she spend on both rent and groceries
rent = 720/3 = 240
remaining = 720 - 240 = 480
.75 * 480 = groceries = 360
so
240 + 360
To find out how much money Joanne Kearns spends on both rent and groceries, we need to calculate each expense step by step.
Step 1: Calculate the amount Joanne Kearns spends on rent.
She spends 1/3 of her money on rent, so we need to find 1/3 of her weekly income. To do this, we multiply her weekly income (720 pounds) by 1/3:
Rent = 720 pounds × 1/3 = 240 pounds
Step 2: Calculate the remaining money after paying rent.
After paying rent, Joanne has a remaining 2/3 of her weekly income. To find this amount, we subtract the rent from her weekly income:
Remaining money = 720 pounds - 240 pounds = 480 pounds
Step 3: Calculate the amount Joanne Kearns spends on groceries.
She spends 3/4 of the remaining money on groceries, so we need to find 3/4 of the remaining amount. To do this, we multiply the remaining money by 3/4:
Groceries = 480 pounds × 3/4 = 360 pounds
Therefore, Joanne Kearns spends a total of 240 pounds on rent and 360 pounds on groceries.
