An attractive image depicting a grocery store scene where a myriad of donuts are being sold for $0.75 each. Ensure that the grocery store scene is bustling with a diverse range of people including Caucasian male employee, Hispanic female customers, Middle-Eastern child picking out his favourite donut, and South-East Asian elderly man counting his coins in preparation to make the purchase. Show the price tag displaying $0.75 per donut. Reflect the mathematical aspect of the question subtly in the image composition, but do not illustrate any equations in the image.

A grocery store charges $0.75 per donut. Which equation can be used to find c, the total cost, in dollars, to buy d donuts?(2 points) Responses c = 0.75 + d c = 0.75 + d c = 0.75d c = 0.75 d d = 0.75 + c d = 0.75 + c d = 0.75c

c = 0.75d
