The percent increase is: 13.8%

Step-by-step explanation:

The percent increase is given by:

Percent\ increase=\frac{Increase}{Original\ price}*100

Where

increase= New\ price - Old\ price

Here

New price = $2.48

Old Price = $2.18

So,

Increase = 2.48 - 2.18\\= 0.3

Percent\ increase = \frac{0.3}{2.18} * 100\\=0.1376*100\\=13.76\%

Rounding off to nearest tenth

13.8\%

The percent increase is: 13.8%

If Joe wants to spend 35% of his income on rent, what percentage of income will he be able to spend on other things?
Andrew [12]

Answer:

65%

Step-by-step explanation:

Given the percentage of amount of money spends on rent is 35%

Total money spend = money spent on rent + money spent on other things

Here total money spent = total money he got as income = 100%

Money spent on other things = total money spent - money spent on rent

Money spent on other things = 100 - 35 = 65%

Therefore the percentage of amount spend on other things are 65%
