Select the correct answer.

Ben is decorating his home with vases of flowers. He bought glass vases that cost [tex]$\$[/tex]22[tex]$ each and ceramic vases that cost $[/tex]\[tex]$14$[/tex] each. The total cost of the vases came to more than [tex]$\$[/tex]172[tex]$. Also, Ben bought no more than 10 vases in all.



Which system of inequalities can be used to determine the number of glass vases, $[/tex]x[tex]$, and the number of ceramic vases, $[/tex]y[tex]$, that Ben could have bought?



A. $[/tex]14x + 22y \geq 172[tex]$

$[/tex]x + y < 10[tex]$



B. $[/tex]14x + 22y > 172[tex]$

$[/tex]x + y \leq 10[tex]$



C. $[/tex]22x + 14y \geq 172[tex]$

$[/tex]x + y < 10[tex]$



D. $[/tex]22x + 14y > 172[tex]$

$[/tex]x + y \leq 10$

Answer :

To solve this problem, we need to determine the system of inequalities that reflects the constraints given:

1. Cost Constraint: Each glass vase costs [tex]$22, and each ceramic vase costs $[/tex]14. Ben's total spending on vases is more than [tex]$172.

2. Quantity Constraint: Ben bought no more than 10 vases in total.

We'll use the following variables:
- \( x \) represents the number of glass vases.
- \( y \) represents the number of ceramic vases.

Step 1: Formulate the Cost Inequality

The total cost of the vases can be calculated using the price of each type of vase and the quantities purchased:
- The cost for glass vases is \( 22x \).
- The cost for ceramic vases is \( 14y \).

The total cost of these vases is more than $[/tex]172, so we have the inequality:
[tex]\[ 22x + 14y > 172 \][/tex]

Step 2: Formulate the Quantity Inequality

The problem states that the total number of vases is no more than 10. This gives us the inequality:
[tex]\[ x + y \leq 10 \][/tex]

Step 3: Combine the Two Inequalities

The system of inequalities that represents the problem is:
1. [tex]\( 22x + 14y > 172 \)[/tex]
2. [tex]\( x + y \leq 10 \)[/tex]

Thus, the correct choice from the given options is:
D.
[tex]\[ 22x + 14y > 172 \][/tex]
[tex]\[ x + y \leq 10 \][/tex]

This system respects the conditions given — that Ben's total cost for vases is more than $172 and that he bought no more than 10 vases in total.
