Answer:
Last month the grocery store sold 578.88 gallons of ice cream and 632.8 pounds of broccoli.
Step-by-step explanation:
Since a grocery store manager notices that this month her store sold a total of 521 gallons of ice cream, which represents a decrease of 10% from last month, and on the other hand, her store sold 791 pounds of broccoli this month, which It represents an increase of 25% from last month, to determine how much ice cream and broccoli did the store sell last month, the following calculation must be performed:
Ice cream = 100 - 10 = 90
90 = 521
100 = X
100 x 521/90 = X
52,100 / 90 = X
578.88 = X
Broccoli = 100 + 25 = 125
125 = 791
100 = X
100 x 791/125 = X
79,100 / 125 = X
632.8 = X
Therefore, last month the grocery store sold 578.88 gallons of ice cream and 632.8 pounds of broccoli.

According to the "BODMAS rule" firstly performing "division".

Now, performing "addition and opening round brackets".

Now, opening "square brackets".
Now, "dividing 15 by 3".
∴ The Answer is -5.
<u>BODMAS</u> rule is an acronym used to remember the order of operations to be followed while solving expressions in mathematics.
It stands for :-
- ↠ B - Brackets,
- ↠ O - Order of powers or roots,
- ↠ D - Division,
- ↠ M - Multiplication
- ↠ A - Addition,
- ↠ S - Subtraction.
It means that expressions having multiple operators need to be simplified from left to right in this order only.
First, we solve brackets, then powers or roots, then division or multiplication (whatever comes first from the left side of the expression), and then at last subtraction or addition.
- ↠ Addition (+)
- ↠ Subtraction (-)
- ↠ Multiplication (×)
- ↠ Division (÷)
- ↠ Brackets ( )
