At an ice cream store, a family ordered 4 banana splits and 5 hot fudge sundaes, paying a total of $27 for their order. The next customer ordered 5 banana splits and 5 hot fudge sundaes and paid $30. How much does each item cost?

both items are $3 each

Step-by-step explanation:

amos: luvnonxistent

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
