Leslie can buy her dog's food at Petco for $25 and receive 9 packs with four cans in each. Leslie can buy the same food at Petsmart for the same price with 7 packs of six cans in each. Which store should Leslie buy her dog food from?

Leslie should buy her dog food from Petsmart  because the price per can is cheaper

Step-by-step explanation:

Step one;

given data

At Petco, we are told that she receives 9 packs with four cans each for $25

Hence Petco gives a total of 9*4= 36cans

the cost of each can will be 25/36

=$0.69 per can

Step two:

At Petsmart, we are told that she receives 7 packs with six cans each for $25

Hence Petsmart gives a total of 7*6= 42cans

the cost of each can will be 25/42

=$0.59 per can

Leslie should buy her dog food from Petsmart  because the price per can is cheaper

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
