Accepted Solution

A:

Answer:Single tomato=$1,32Single ear of corn=$3,21Step-by-step explanation:For this we need to express 2 inequalities with 2 unknown lettersFor Deandre we have:15(x)+12(y)=58,32x being the price for tomato and y for ears of cornFor Eduardo we can use the same letters for price of tomatoes and ears of corn:3(x)+10(y)=34,16We can clear one letter in function of the other in one inequality3x=34,16-10yx=(34,16-10y)/3and use this expression to solve the first15((34,16-10y)/3)+12y=58,32170,8-50y+15y=58,32112,48=35y3,21=y and y represents the price for each ear of corn15x+12(3,21)=58,3215x=19,8x=1,32x represents the price for each tomato
