Question

16. At Dunn's grocery store, small bas of goldfish crackers cost $3 and large bags cost $5. This month, if they sold a total of 280 bags of goldfish crackers and made $1,200; how many large bags did they sell?

Answer 1

Let’s use algebra to solve this problem. Let x be the number of large bags sold, and y be the number of small bags sold. We know that:

x + y = 280 (total number of bags sold) 5x + 3y = 1200 (total revenue)

We can solve for x by multiplying the first equation by three and subtracting it from the second equation:

5x + 3y = 1200 -(3x + 3y = 840)

2x = 360 x = 180

Therefore, Dunn’s grocery store sold 180 large bags of goldfish crackers this month.
