Carolina moved the hand of a spinner 270 degrees, as shown below. What fraction of a complete turn through a circle is 270 degrees? A 3/360 or B 27/360 or C 90/360 or D 270/360

You can use system of linear equations to find the solution.

The  cost to customer to buy 5 tulips and 6 roses will be $17.75

Given that:

• The price of all tulips are same.
• The price of all roses are same.
• Price of 7 tulips and 9 roses is $25.90
• Price of 4 tulips and 8 roses is $19.80

To find:

Cost of buying 5 tulips and 6 roses.

Naming the prices:

• Let price of one tulip be $x
• Let price of one rose be $y

Forming system of equations:

By given data, we have:

7 tulip + 9 roses costs $25.90

or

And

4 tulips + 8 roses costs $19.8

or

Thus, we have two equations.

Using method of substitution:

From equation first, we have:

Substituting this value in second equation, we get:

Thus, we have:

Thus, the price of a tulip = x = $1.45

and the price of a rose = y = $1.75

Now, calculating price of 5 tulips and 6 roses:

Thus, the cost to a customer who buys 5 tulips and 6 roses would be $17.75

It will cost a customer $17.75 to buy 5 tulips and 6 roses.

Step-by-step explanation:

Let,

Cost of one tulip = x

Cost of one rose = y

According to given statement;

7x+9y=25.90       Eqn 1

4x+8y=19.80       Eqn 2

Multiplying Eqn 1 by 4

Multiplying Eqn 2 by 7

Subtracting Eqn 3 from Eqn 4

Dividing both sides by 20

Putting y=1.75 in Eqn 1

Dividing both sides by 7

Cost of 5 tulips and 6 roses = 5x+6y = 5(1.45)+6(1.75) = 7.25+10.50 = $17.75

It will cost a customer $17.75 to buy 5 tulips and 6 roses.
