Final answer:
The total cost equation for rice and a bottle of seasoning is C = 1.30p + 1. To graph this relationship, start at point (0,1) and use a ray with a slope of $1.30 to represent the increasing cost with additional pounds of rice.
Step-by-step explanation:
To graph the total cost of rice and a bottle of seasoning versus pounds of rice, you would typically use the equation C = pr + s, where C is the total cost, p is the number of pounds of rice, r is the cost per pound of rice, and s is the cost of the seasoning. Here, you're told five pounds of rice cost $6.50, so to find the cost per pound, you would divide $6.50 by 5, giving you $1.30 per pound for rice. Since the rice seasoning costs $1.00 per bottle, your equation is C = 1.30p + 1.
To sketch this using a ray tool, you would start at the point (0,1) on a graph, since even with no rice (p=0), you still have the cost of one bottle of seasoning which is $1. Then, you would draw a ray with a slope of 1.30, representing the cost per pound of rice, starting at (0,1) and extending upwards to the right, since the cost increases with each additional pound of rice.
