Question 1098820
x = number of orchid bunches.
y = number of rose bunches.


each orchid bunch earns 25 dollars and each rose bunch earns 30 dollars and she earns a total of 390, therefore:


25x + 30y = 390


she sells 4 times as many orchid bunches as rose bunches, therefore:


x = 4y


replace x with 4y in 25x + 30y = 390 to get:


25 * (4y) + 30y = 390


simplify to get 100y + 30y = 390


combine like terms to get 130y = 390


solve for y to get y = 390 / 130 = 3


if y = 3, then x = 4y must be equal to 12.


she sold 12 orchid bunches and 3 rose bunches.


12 * 25 = 300
3 * 30 = 90
total is 390.


the question asked how many flowers did she sell.


each orchid bunch contains 20 flowers and each rose bunch contains 10 flowers.


12 * 20 + 3 * 10 = 240 + 30 = 270 flowers total.


i believe that's what they are asking for.
