Step-by-step explanation:
23B) The equation is 24-x(7)=10
Because she spends twenty four dollars on seven rings which we don't know how much it costs giving us a change of ten dollars
23C) The equations solution:
24-x(7)=10
24-x*7=10
-7x=10-24
-7x=-14
-7x/-7=-14/-7
x=2
23D) Twenty four dollars is spent on seven rings that costs two dollars each, giving a total of fourteen dollars spendings. Therefore the change is ten dollars.
