Answer:
[tex]x+y\leq 10[/tex]
[tex]15x+10y\leq 150[/tex]
Explanation:
However, the question did not tell us how many items in total, we will create a concept, say she must buy a total of 10 items, that both leash and collars
Step one:
let leash be x, and let collar be y
given data
cost of one leash =$15
cost of one collar= $10
total amount= $150
Step two:
The systems of the equation for the situation is
[tex]x+y\leq 10[/tex]-------1 this is for the number of each item
[tex]15x+10y\leq 150[/tex]------2 this is for the cost of all the items combined
