Answer:
$272 left from her budget spend for month.
B is correct.
Step-by-step explanation:
Clarissa has a budget of $1,200 a month to spend for rent and food.
She has already spent $928 this month.
Let Clarissa has left $x amount spend for month.
Total budget is $1,200
Thus, sum of spent and remain would be less than equal to 1200
According to question:
Hence, $272 left from her budget spend for month.

Answer:
18. compound interest
19. simple interest
20. simple interest
Step-by-step explanation:
For these problems, the initial balance is irrelevant. All that matters is the multiplier of that balance. For simple interest at rate r for t years, the multiplier is ...
simple interest multiplier = (1 +rt)
For interest compounded annually, the multiplier of the initial balance is ...
compound interest multiplier = (1 +r)^t
A spreadsheet can do the computations for you.
___
As an example of the computations involved, consider problem 19:
simple interest multiplier = 1 + 0.13·6 = 1.78
compound interest multiplier = 1.10^6 = 1.771561
The latter is less than the former, so the simple interest account will have the (slightly) greater balance at the end of 6 years.
