Answer: cost of 1 pot of ivy = $12
Cost of 1 rose bush =$ 10
Step-by-step explanation:
Step 1
Let rose bushes be represented as r
and pot of ivy be represented as p
such that Amy who spent 82 dollars on 7 rose bushes and 1 pot of ivy can be expressed as
7 r + p = 82----- eqn 1
Rob who spent 74 on 5 rose bushes and 2 pots of ivy can be expressed as
5r +2 p = 74----- eqn 2
Step 2
Solving
7 r + p = 82----- eqn 1
5r +2 p = 74----- eqn 2
By elimination method Multiply eqn 1 by 5 and eqn 2 by 7
35r+ 5p= 410--- eqn 3
35r+ 14p =518--- eqn 4
Subtracting eqn 4 from eqn 3
9p = 108
p = 108/9
p=12
p = pot of ivy = $12
therefore rose bush wll be ( from equation 1)
7r+ p= 82
7r=82-12
7r= 70 r= 70/7
r= rose bush =$ 10
To solve the problem it is trial and error since we
don’t know how many hotdogs and bottled water was sold. To trim down to
problem, negative values and decimal values are not included because there is
no negative amount and a decimal amount.
The equation is
4x + 2y > 12
At (0,6)
4(0) + 2(6) > 12
12 > 12 so it is wrong
At ( 2,1)
4(2) + 2(1) > 12
10 > 12 correct
At (1, 3)
4(1) + 2(3) > 12
10 > 12 correct
At (2,2)
4(2) + 2(2) > 12
12> 12 wrong
