Aprice of a cake is c pounds . the total cost of buying 20 cakes is tpuonds. write a formula for t in terms of c

For a single cake: c pounds.
for 20 cakes: t poucnds.
Thus, 20c=t
t=20c

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
