Answer: He would make $36 for 12 pounds of strawberries He would make $196 for 49 pounds of blueberries
He would make 3S if he sold S pounds of strawberries He would make 4B if he sold B pounds of blueberries
Working: We know that strawberries are $3/pound so $3 x 12pounds = $36 We know that blueberries are $4/pound so $4 x 49pounds = $196
The letters represent the amount of pounds of fruit being bought so the calculation for that is ($ x pounds) so you would write this but without assigning a numerical value to the amount. So if the strawberries are $3/pound and Luke sold ‘s’ pounds then it would be 3S (or 3xS but that is already assumed). The same goes for the blueberries. We know that they are $4/pound so it would be 4B.
Sorry if this doesn’t make any sense but I hope this helped
