One apple weighs 75 grams and one orange weighs 40 grams. Determine the weight of x apples and y oranges.

Answer 1

$$\begin{gathered} \mathrm{Weight}\mathrm{of}\mathrm{an}\mathrm{apple}=75\mathrm{grams} \\ \mathrm{Weight}\mathrm{of}\mathrm{an}\mathrm{orange}=40\mathrm{grams} \\ \mathrm{Weight}\mathrm{of}x\mathrm{apples}=75\times x=75x\mathrm{grams} \\ \mathrm{Weight}\mathrm{of}\mathrm{y}\mathrm{oranges}=40\times \mathrm{y}=40y\mathrm{grams} \\ \mathrm{Total}\mathrm{weight}\mathrm{of}x\mathrm{apples}\mathrm{and}y\mathrm{oranges}=(75x+40y)\mathrm{grams} \end{gathered}$$
