Answer:
Cost of 1 bushes = a = $9
Cost of 1 tree = b = $73.5
Step-by-step explanation:
Given:
13 bushes and 4 trees cost = $411
Missing;
6 bushes and 2 trees cost = $201
Find:
Value of bushes and tree
Computation:
Cost of 1 bushes = a
Cost of 1 tree = b
So,
13a + 4b = 411 ...........eq1
6a + 2b = 201 ................eq2
From Eq1 and Eq2
Cost of 1 bushes = a = $9
From eq 1
13a + 4b = 411
13(9) + 4b = 411
Cost of 1 tree = b = $73.5
Answer:
The maximum number of toys you can afford to buy is 40
Step-by-step explanation:
Let
x -----> the number of toys
we have the compound inequality
Divide into two inequalities
-----> inequality A
----> inequality B
<em>Solve the inequality A</em>
Divide by 11 both sides
Rewrite
<em>Solve the inequality B</em>
Divide by 11 both sides
The solution for x is the interval ----> [13,40}
Remember that the number of toys must be a whole number
The domain is all whole numbers greater than or equal to 13 toys and less than or equal to 40 toys
therefore
The maximum number of toys you can afford to buy is 40
