The formula for percentage increase is given as:-
Percentage Increase = ( New Price - Old Price ) /old price * 100
old price = $525
New Price = $650
lets plug the values in the formula
Percentage Increase =
Hence the price increases by 24%
Answer: x = 7 and y = 2
Since x is already defined for us, we can substitute for it in the second equation which gives us:
(5y - 3) + y = 9
6y - 3 = 9
6y = 12
y = 2
Then find x using y
x = 5(2) - 3
x = 10 - 3
x = 7
You can buy 14 cans max. It totals out at $9.66, with 15 bringing it 35 cents over the limit. Using trial and error with multiplication is one way to solve it.
The answer is A) 5b
Lets try an example:
Lets say we have 3 boxes in total of both board games. We can solve for b since b = 3 in the example.
= 15 dice in total
We can check our answer by adding the amount of dice per box.
2 + 3 = 5
Then multiplying by the number of boxes.
5 * 3 = 15 dice total
