One apple weighs 75 grams and one orange weighs 40 grams. Determine the weight of x apples and y oranges.
Weight of an apple =75 grams
Weight of an orange=40 grams
Weight of x apples =75×x
=75x grams
Weight of y oranges =40×y=40y grams
Therefore, total weight of x apples and y oranges =(75x+40y) grams
