-9x-35 is the answer. I hope this helps!
Answer:
There would be a 56% increase
Step-by-step explanation:
We need to find the amount of change before we can find the percent of change. We'll take the greater value, 78, and subtract the lesser value, 50. 78 - 50 = 28. We then take this amount of change and put it over the original amount, Percent of change = Amount of change/ original amount or for this problem, 28/50. We then use that as a division equation for 28 divided by 50. 28 divided by 50 = 0.56. Finally we move the decimal to the right two times and we can then find the percentage increase.
12 is the answer to this problem. Remember PEMDAS.
Answer:
The profit of the bakery for this batch of rolls is C. $ 132
Step-by-step explanation:
You know the following this about the problem:
- xy=300 is the total cost of the production of the rolls, where x is the cost of the rolls and y is the number of rolls.
- Day 1 the bakery sold 4/5 of the rolls at 1.50 its value.
- Day 2 the bakery sold 1/5 of the rolls ar 0.8 of the price of Day 1.
The total gain of the sales is:
Day 1 + Day 2
and you know that xy =300, then the total gain is:
And the profit is the total gain less the total cost:
Profit = 432-300=132
It is pi x 11(x2 to get diameter) so it would be 69.08...
