Jack's spending: (per week)

Sweets: 15%

Magazines: 35%

Total spendings =15% + 35% = 50%

Savings = 100%-50% = 50%

i.e., Every week, Jack spends 15% on sweets, 35% on Magazines and remaining 50%, goes into savings.

So, if the weekly pocket of Jack is \$100, he spends \$15 on sweets, \$35 on Magazines and saves the rest \$50.

Hope this helps.

Let Jack has \$100.

Spendings on sweets =\$15

Spendings on Magazines = \$35

ans total spendings =\$15+\$35=\$50

Savings=Total money-total spendings

= \$100-\$50

=\$50

100% is the whole.

So, from your question, Jack spends 35% on magazines. So, that is 35% out of 100%. Jack spends 15% on sweets, so that is 15% out of 100%. So, with that, the total percentage of money he spends on both sweets AND magazines would be 15% + 35% = 50%.

So, be spends 50% of his money on those things.

Next, we have to find how much money he saved. Remember that the whole amount of money he has is 100%. He spent 50% of that 100%, so all that is left is 50%. 100% - 50% = 50%.

Therefore, he saved 50%.

Let's look at this a different way in case you don't understand.

Let's say that Jack has \$10. \$10 is all of bis pocket money, so that is 100%. If he spends 35% of that money, or \$3.50 of that money on magazines and 15%, or \$1.50 for sweets, then he spend \$5 in all. If we do \$10, the starting amount of money he had, and subtract what he spent out of that, \$5, we get \$5 left.

Hope I helped!
