Janaya buys a postcard from each travel destination she visits. Before starting her travels this year, Janaya had 20 postcards.
MrRa [10]

Answer:

The percentage increase in Jayana's postcard collection is 15%

Step-by-step explanation:

Jayana had 20 postcards last year

With 3 more postcards this year

From the given equation Quantity = Percent x Whole

Here;

Let P = Percent/100%

Quantity = Increment in postcard = 3 postcards

Whole = The total postcards from last year = 20 postcards

Hence,

3 postcards = P x 20 postcards

P = 3/20 = 0.15

Recall P = Percent/100%

∴ Percent = P x 100% = 0.15 x 100% = 15%

The percentage increase in Jayana's postcard collection is 15%

zhannawk [14.2K]

Answer:

Step-by-step explanation:

Given:

Fuel expense in last year =  $800

Fuel expense in this year =  $960

To Find:

The percentage of increase

Solution:

Let the percentage increase be X

Then X  =\frac{\text{final value}-\text{starting value}}{\text{starting value}}\times 100

Now substituting the values we get,

X =\frac{960-800}{800}\times 100

X =\frac{160{800}\times 100

X =0.2 \times 100

X= 20%
