Q. marth!POINTSPOINTSGAMEReviewChange Assignmentd help?First try was incorrectHide SThere is a proportional relationship between the total cost (in dollars), y, and the number of jackets Nguyen buys, x. He purchased 17 jackets for $136.Graph this proportional relationship.
Calculate cost per jacket: Figure out the cost per jacket by dividing the total cost by the number of jackets.$136/17 jackets = $8 per jacket.
Write total cost equation: Write the equation for the total cost y in terms of the number of jackets x.y=8x
Plot point on graph: To graph this, start by plotting the point (17,136) since we know Nguyen bought 17 jackets for \$\(136\).
Graph proportional relationship: Since it's a proportional relationship, the graph will be a straight line that passes through the origin \((0,0)\) and the point \((17, 136)\).
