Answer:
270 flowers total she sell Together.
Step-by-step explanation:
According to the Question,
- Given, A florist arranges some orchids in bouquets of 20 and some roses in bouquets of 10.
Let, x = number of orchid bunches & y = number of rose bunches.
-
Now, She sells each orchid bouquet for $25 and each rose bouquet for $30. She earns a total of $390
Therefore, 25x + 30y = 390 ⇒⇒ Equation 1
she sells 4 times as many orchid bunches as rose bunches,
Therefore, x = 4y ⇒⇒ Equation 2
- Put The Value Of Equation 2 in Equation 1, We get
25 × (4y) + 30y = 390
100y + 30y = 390
130y = 390 ⇔ y = 390 / 130 ⇒ 3
if y = 3, then x = 4y must be equal to x= 12.
Thus, she sold 12 orchid bunches and 3 rose bunches.
- Verify, 25x + 30y = 390 ⇔ 12 × 25 + 3 × 30 = 390 (All okay)
Now, Each orchid bunch contains 20 flowers and each rose bunch contains 10 flowers.
- 12 × 20 + 3 × 10 = 240 + 30 ⇔ 270 flowers total she sell Together.

Answer:
0.75 3/4, 0.30 3/10, 0.05 1/20
Step-by-step explanation:
25x3 is 75 but because its 75 cents its 0.75
and 3/4 means 0.75 (3 divided by 4 is 0.75)
10x3 is 30 but because its 30 cents its 0.30
and 3/10 means 0.30 (3 divided by 10 is 0.30)
1x5 is 5 and because its 5 cents its 0.05
and 1/20 means 0.05 (1 divided by 20 is 0.05)
Answer:
3x(10x10x10): 3x(1000): 3000-7000: -4000. (8x(-5)): -40. (4x4) +(2x2): (16 +4): 20
