Answer:

<u>A cart of groceries that costed US$ 160 in 2005, costs US$ 197.49 in 2010 at an average rate of 4.3% of inflation.</u>

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Cost of cart of groceries in 2005 = US$ 160

Period of inflation analysis = 5 years

Inflation average rate = 4.3 % compounded annually

2. Let's find the future value of the cost of a cart of groceries in 2010, using the following formula:

FV = PV * (1 + i) ⁿ

PV = Cost of cart of groceries in 2005 = US$ 160

number of periods (n) = 5 (Period of inflation analysis = 5 years)

Inflation average rate (i) = 4.3% = 0.043

Replacing with the real values, we have:

FV = 160 * (1 + 0.043) ⁵

FV = 160 * (1.043) ⁵

FV = 160 * 1.234302311

FV = 197.49 (Rounding to two decimal places)

Answer:

$\left \{ {{x = -15} \atop {y=3}} \right.$

Step-by-step explanation:

$\left \{ {{x + 5y = 0} (1) \atop {3y + 2x = -21}(2)} \right. \left \{ {{x = -5y} \atop {3y + 2x = -21}} \right. \left \{ {{x = -5y} \atop {3y + 2*(-5y) = -21}} \right. \left \{ {{x = -5y} \atop {3y - 10y = -21}} \right. \\ \left \{ {{x = -5y } \atop {-7y = -21}} \right. \left \{ {{x = -5y} \atop {y= 3 }} \right. \left \{ {{x = -5 * 3} \atop {y=3}} \right.=> \left \{ {{x=-15} \atop {y=3}} \right.$
