Rick Ross owns a flower shop named Ricky Rosé. He ordered 200 flowers for Mother's Day. He ordered roses at $1.50 each, carnations at $5.75 each, and daisies at $2.60 each. He ordered mostly roses, and 20 fewer carnations than daisies. The total order came to $589.50. How many of each type of flower was ordered?

80 roses, 50 carnations and 70 daisies were ordered.

Step-by-step explanation:

From the information provided, you can write the following equations:

x+y+z=200 (1)

1.50x+5.75y+2.60z=589.50 (2)

z=y+20 (3)

First, you can replace (3) in (1) and (2):

x+y+y+20=200

x+2y=180

1.50x+5.75y+2.60(y+20)=589.50

1.50x+5.75y+2.60y+52=589.50

1.50x+8.35y=537.50

Now, you have 2 equations:

x+2y=180 (4)

1.50x+8.35y=537.50 (5)

You can solve for x in (4):

x=180-2y (6)

Then, you can replace (6) in (5) and solve for y:

1.50(180-2y)+8.35y=537.50

270-3y+8.35y=537.50

5.35y=267.50

y=267.50/5.35

y=50

You can replace the value of y in (6) to find x:

x=180-2(50)

x=180-100

x=80

Finally, you can replace the value of y in (3) to find z:

z=y+20

z=50+20

z=70

According to this, the answer is that 80 roses, 50 carnations and 70 daisies were ordered.

i think the amount would be $140.62

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
