Answer:
115ft^2
Step-by-step explanation:
10 * 11.5 = 115
We want to increase by 15% so we want 100% plus 15% which means 115%
Since we want 115% lets make the calc:
65 pizzas ----------- 100%
x pizzas ------------- 115%
Multiply in cross
65 . 115 = 100.x
7475 = 100.x
x = 74,75
Since we cant sell 74 pizzas and 0,75 pizza we will sell 75 pizzas
So we need to sell 75 pizzas to employees receive the bonus
The man is 27 years old and the son is 9 years old.
We can write the son's age as 'x', and therefore write the man's age as 4x. In 3 years, both their ages will increase by 3, so the son's age is now x + 3, and the man's age is 4x + 3.
We are told that the man is now 3 times older than his son, which means his current age, 4x + 3, is the same as 3 times the son's current age, which is x + 3.
Therefore we can write an equation:
4x + 3 = 3(x + 3)
4x + 3 = 3x + 9
- 3x
x + 3 = 9
- 3
x = 6
We can now substitute this in to find their current ages:
Son's age = x + 3 = 6 + 3 = 9
Man's age = 4x + 3 = 24 + 3 = 27
I hope this helps! Let me know if you have any questions :)
