Question

Cheese sticks that were previously priced at

Answer 1

Answer

Find out the percent increase in the price per cheese stick.

To prove

As given

Cheese sticks that were previously priced at  "5 for $1" are now "4 for $1".

i.e previously the price of the 5 cheese stick is $1 .

$one\ cheese\ sticks\ price = \frac{1}{5}$

                                      = 0.2

Now the price of the 4 cheese stick is $1 .

$one\ cheese\ sticks\ price = \frac{1}{4}$

                                      = 0.25

Change in price per cheese stick =  now price - previous price

                                                       = 0.05

Formula

$Percentage\ increase = \frac{Change\ in\ price\ per\ cheese\ stick\times 100}{Previous\ price\ per\ cheese\ stick}$

Put all the value in the formula

$Percentage\ increase = \frac{0.05\times 100}{0.2}$

                                            = 25%

Therefore the percent increase in the price per cheese stick is 25%.

                                               

Answer 2

The price of cheese sticks went from 5 for $1 ( $0.20) to 4 for $1 ($0.25)
.25-.20= .05
.05/.20= 25% increase in price per cheese stick
