Dimas [21]

Answer:

$2400 in A rated bond and $3000 in B rated bond.

Step-by-step explanation:

We have been given that Maria has recently retired and requested an extra ​$444.00 per year in income.

We can represent this information in an equation as:

A+B=5400...(1)

She has $5400 to invest in an​ A-rated bond that pays 10% per annum or a​ B-rated bond paying 6% per annum.

0.10A+0.06B=444...(2)

From equation (1), we will get:

A=5400-B

Substitute this value in equation (2):

0.10(5400-B)+0.06B=444

540-0.10B+0.06B=444

540-0.04B=444

540-540-0.04B=444-540

-0.04B=-96

\frac{-0.04B}{-0.04}=\frac{-96}{-0.04}

A=2400

Therefore, Maria should invest $2400 in A-rated bond.

Substitute A=2400 in equation (1):

2400+B=5400

2400-2400+B=5400-2400

B=3,000

Therefore, Maria should invest $3000 in B-rated bond.

Eugene                        Chloe                       Stake Out                  not Limousine

Therefore, from the given conditions, David and Andrea spent their evening at Water World fun park and they got there by taxi.

At the gas station each liter of gas costs $3 but there is a promotion that for every beverage you purchase you save 0.20 cents
KATRIN_1 [288]
When a relationship between two variables is proportional, it means that there is a constant ratio between the two variables. In this case, the answer is yes, there is a proportional relationship between total savings on gas and the number of beverages purchased.

You save $0.20 on gas for every beverage you buy.
Let s=dollars saved on gas, and b=# of beverages purchased
s=.2b
or
s=b/5
