Question

Suzie's Nursery is having a sale on two kinds of plants, venus fly traps and bonsai trees.

Venus fly traps cost $3 per plant and bonsai trees cost $5 per plant. At the end of the first
day of the sale, Suzie noted that there were 29 plants sold for a total of $121. How many
of each kind of plant did she sell?

Answer 1

Venus fly trap = 12

Bonsai tree = 17

Explanation:

Given that :

Venus fly trap = $3per plant

Bonsai tree = $5 per plant

Number of plants sold = 29

Total cost of plant sold = $121

Let venus fly trap = x ; bonsai tree =y

x + y = 29 ___ (1)

3x + 5y = 121 ____(2)

From (1) :

x = 29 - y

In (2):

3(29 - y) + 5y = 121

87 - 3y + 5y = 121

87 + 2y = 121

2y = 121 - 87

2y = 34

y = 34/2

y = 17

x = 29 - 17

x = 12

Hence,

Venus fly trap = 12

Bonsai tree = 17
