Wanda has 4 vases of flowers. Some of the vases contain 10 orchids. The other vases contain 3 begonias. There are 19 flowers in the vases in total. How many vases of each type of flower does Wanda have?
r = orchid vases 10 * r = 3 flows.. in orchid vases
(4-r) = begonia vases 3 * (4-r) = # flows. in begonia vases summed they equal 19
10r + 3*(4-r) = 19 solve for 'r' then orchids = 10r and begonia = 3 (4-r)
Wanda has 4 vases of flowers.
Let 'x' number of vases contain 10 orchids,
then (4-x) number of vases contain 3 begonias.
Then, total number of flowers = 10(x) + 3(4-x)
Given that there are 19 flowers in vases total
So, 10(x) + 3(4-x) = 19
10x + 12 - 3x = 19
7 x = 7
x = 1
So, Wanda have 1 vase of 10 orchids and 4-1 = 3
number of vases containing 3 begonias.
