Because of the way you wrote the problem I am unsure if you meant y^4*y^3 or 4y*3y. So I included the solution to both. y^4*y^3 = y^7 This is because you add exponents when multiplying them. If you meant 4y*3y then the answer is as follows: 4y*3y = 12y
Well on answer could be $238-$28=210 divided by 3 = $70 each also another one is $208-$28=180 and then if u divide $180 by 3 u will get a awser of $60 each
