Your opening balance this month was $1,664.00. In the last thirty days you made the following purchases: $27.35, $54.15, and $12

Viktor [21]

Answer:

$1661.41875

Step-by-step explanation:

Since you purchased the following

$27.35,$54.15,$125

So let's add up

27.35+54.15+125

206.5

So let's determine the interest

1.25% of 206.5

1.25/100 ×206

258.125/100

2.58125

So we will have to deduct 2.58125 from the initial amount

1664-2.58125

1661.41875

So the amount left is $1661.41875

Kylie went into a grocery store and bought 3 apples and 4 bananas, costing a total of $6.50. Lily went into the same grocery sto

Katyanochek1 [597]

The system of equations that could be used to determine the price of each apple and the price of each banana is:

3x + 4y = 6.50

10x + 5y = 17.50

Where x is the price of each apple and y is the price of each banana

Step-by-step explanation:

The given is:

Kylie went into a grocery store and bought 3 apples and 4 bananas, costing a total of $6.50
Lily went into the same grocery store and bought 10 apples and 5 bananas, costing a total of $17.50

We need to write a system of equations that could be used to determine the price of each apple and the price of each banana

Assume that x represents the price per apple, and y represents the price per banana

∵ The price of each apple is $x

∵ The price of each banana is $y

∵ Kylie bought 3 apples and 4 bananas for a total $6.50

- Multiply x by 3 and y by 4, then add the products and equate

the sum by 6.50

∴ 3x + 4y = 6.50 ⇒ (1)

∵ Lily bought 10 apples and 5 bananas for a total $17.50

- Multiply x by 10 and y by 5, then add the products and equate

the sum by 17.50

∴ 10x + 5y = 17.50 ⇒ (2)

The system of equations that could be used to determine the price of each apple and the price of each banana is:

3x + 4y = 6.50

10x + 5y = 17.50

Where x is the price of each apple and y is the price of each banana

For the years between 1990 and 2009, the regression equation yˆ=0.15x+3.95 models the minimum wage, where x is the number of yea

Jlenok [28]

Answer:

1.) The minimum wage increased by $0.15 per year.

5.) The minimum wage in 1990 was $0.15.

7.) The minimum wage in 1990 was $3.95.

Step-by-step explanation:

given that the years between 1990 and 2009, the regression equation yˆ=0.15x+3.95 models the minimum wage.

where x = 19 years

The slope = 0.15

The intercept = 3.95

The best statement for interpretation of the slope and interpretation of the y-intercept are:

1.) The minimum wage increased by $0.15 per year.

5.) The minimum wage in 1990 was $0.15.

7.) The minimum wage in 1990 was $3.95.

A cyclist rides her bike at a rate of 8 miles per hour. What is this rate in kilometers per hour? How many kilometers will the c

alina1380 [7]

1 mile is equal to 1.6 kilometers, so 8 miles (using a direct proportion) should be equal to 8 * 1.6 = 12.8 kilometers. The cyclist rides at 12.8 kilometers per hour. In four hours, the cyclist would have rode 12.8 * 4 = 48 + 3.2 = 51.2 kilometers.
