Answer:
Bushes are $9.
Bonsai trees are $32.
Step-by-step explanation:
Bushes are b and bonsai trees are t.
15b + 8t = $391
9b + 5t = $241
15b + 8t = $391 × 3 and 9b + 5t = $241 × 5
= 45b + 24t = $1173 and 45b + 25t = $1205
(45b + 24t = $1173) - (45b + 25t = $1205)
t = 1205 - 1173
t = $32
Apply to 15b + 8t = $391.
15b + 32 × 8 = $391
15b = $391 = 32 × 8
15b = $391 - 256
15b = $135
x = ($135 ÷ 15) = $9
