Answer:
The cost of pizza increased by 33%
Step-by-step explanation:
The percentage increase can be calculated as follows;
Old price = $6
New price = $8
Change price = 8 — 6 = $2
Now we'll find the percentage of the old price that will amount to $2
Let the percent be y.
y% of 6 = 2
(y /100) x 6 = 2
6y / 100 = 2
Cross multiply
6y = 200
Divide both side by the coefficient of y i.e 6
y = 200/6
y = 33%
The cost of pizza increased by 33%
