62.4g of sugar is needed to make 8 cakes. How much sugar is needed for 9 cakes?

70.2g

Step-by-step explanation:

62.4 g will make 8 cakes, so to find out how much sugar we need to make

1 cake will divide 62.4 into 8 equal parts.

62.4/8 = 7.8g of sugar is needed to make 1 cake

62.4+7.8 = 70.2g  will make 9 cakes

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
