A grocery store offer 4 cans of store brand vegetables $3.00 On nearby shelves, other brands available at the prices shown below. Which of the offers have a unit rate that is less than the store brand unit rate? Select ALL correct answers. A. 2 cans for $1.25
B. 3 cans for $2.00
C. 4 cans for $3.20
D. 5 cans for $3.60
E. 10 cans for $7.50

The idea is to find out the ‘cost’ aka ‘rate’ for an individual can. Use division to find and figure out a rate per unit. So, divide the number of cans by the price. This will allow us to figure out the the cost of one can. 4 store brand cans / $3.00 = $1.33 per can. Option A is 2 cans / $1.25 = $1.60 per can Option B is 3 cans / $2.00 = $1.50 per can. Option C is 4 cans / $3.20 = $1.25 per can. Option D is 5 cans / $3.60 = $1.38 per can. Option E is 10 cans / $7.50 = $1.33 per can Now that we have found the rate for each brand’s can of vegetables, we can now see which one costs less than the store brands. Looks like Option C is a win. So yes the answer is: C. 4 cans for $3.20
