The answer to your question would be -8
Answer:
She should mix 9 g of powder
Step-by-step explanation:
From the question, we can have a ratio for powder to water
we have 5 g of powder mixed with 45 cm^3 of water
So, for every 1 g, we have 5g/45 cm^3
we have 9 cm^3
So let’s relate this to the bigger water mix
Recall from above; we have the mixing as 1 g per 9 cm^2 of water
1g per 9 cm^2
x g per 81 cm^2
81 * 1 = x * 9
9x = 81
x = 81/9
x = 9g
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
