Answer:
Part A: 30%
Part B: 45000%
Step-by-step explanation:
To get your answer, you have to divide whatever number the down payment is by the number the family is supposed to pay for the studio apartment.
Part A: You need to divide $54.00 by $180.00, when you do that, you get the answer 0.3. You convert it to percentage by doing 0.3 multiplied by 100 which give you 30. Put a percent behind it and you have 30% as your final answer.
Part B: You need to divide 81,000 by 180 which gives you 450. Then you then have to do 450 multiplied by 100 which gives you 45,000. You then add the percentage behind and you have 45000% as your final answer.
The answer is B, because A and C are automatically eliminated because they are subtracting, and the equation that represents the situation is an addition inequality. B is correct because the two parenthesis numbers represents the students attending the fair paying $0.50, and there are 200 students. The 2.25a represents an amount of adults, each paying $2.25.
Answer: B
a+b+c=68
b-3=a
c-5=b
now just solve the system of equations, substitue so that there are only b's in the equation:
a+b+c=68
(b-3) + b + (b+5) = 68
3b=66
b=22
Therefore Barbara is 22
