1. Answer :
The final expression which represents the total amount of money Adam has left :
= [(520 - 320) ÷ 5] + 72
Evaluation = [(520 - 320) ÷ 5] + 72 = [(520 - 320) ÷ 5] + 72 = [200 ÷ 5] + 72 = 40 + 72 = 112 |

Amount of money Lenin has left is $112.
2. Answer :
The final expression which represents the change you will get back :
= $1.55 - 74¢
In the expression above, one value is in dollars and other value is in cents. To simplify the above expression, both the values must be in same unit.
Since 1$ = 100¢, multiply the dollars by 100 to convert it to cents.
= 1.55x100¢ - 74¢
Now, both the values are in the same unit, cents.
Evaluation = 1.55x100 - 74 = 155 - 74 = 81 |

The change will you get back is 81¢.
3. Answer :
Since $1,500 is distributed among two groups equally, amount of money that each group gets :
= 1500/2
First Part :
The expression which represents the amount of money that each child gets in the first part :
= (1500/2) ÷ 3
Evaluation = (1500/2) ÷ 3 = 750 ÷ 3 = 250 |

In the first part, each of the three children gets $250.
Second Part :
The expression which represents the amount of money that each brother gets in the second part :
= (1500/2) ÷ 5
Evaluation = (1500/2) ÷ 5 = 750 ÷ 5 = 150 |

In the second part, each of the five brothers gets $150.
4. Answer :
The expression which represents Andy's present amount :
= 2540 x 2 + 330 - 278
Evaluation = 2540 x 2 + 330 - 278 = 5080 + 330 - 278 = 5410 - 278 = 5132 |
Operation Multiplication Addition Subtraction Result |
The final amount of money in stock is $5132.
5. Answer :
The expression which represents Jessica's expenditure :
= 4x1.60 + 2x1.50 + 1x1.70
Evaluation = 4x1.60 + 2x1.50 + 1x1.70 = 6.40 + 3.00 + 1.70 = 11.10 |
Operation Multiplication Addition Result |
Jessica paid $11.10 in all.
6. Answer :
The final expression which represents the money Dustin at the end of the shopping day :
= 53 + 375 - 35 - 5x17 - 3x25
Evaluation = 53 + 375 - 35 - 5x17 - 3x25 = 53 + 375 - 35 - 85 - 75 = 428 - 35 - 85 - 75 = 393 - 85 - 75 = 308 - 75 = 233 |
