Answer:
3x+4y=7.25
Step-by-step explanation:
according to the 1st equation, the number of pickle is 'x', and number of bag is 'y'.
Then the 2d equation is 3x+4y=7.25
You take the amount paid and divide it by the amount of cheese. So 10.50 divided by 2.5 equals 4.2 and 12.60 divided by 3 equals 4.2 meaning that one pound of cheese costs $4.20
20-12 1/3=7 2/3 or 23/3. so there is a total of 23/3 ft available. We then take half of that for each side. 1/2 of 23/3= 1/2*23/3= 23/6
