Question

2. A ceramic sugar bowl weighs 340 grams when empty. It is then filled withsugar. One tablespoon of sugar weighs 12.5 grams.2a. Write an equation to represent the relationship between the totalweight of the bowl in grams, W, and the tablespoons of sugar, T.2b. When the sugar bowl is full, it weighs 740 grams. How manytablespoons of sugar can the bowl hold? Show your reasoning."

Answer 1

2a.

Let the total number of tablespoons of sugar that filled the bowl be T

Initially, the bowl weighs 340 grams. After putting some T tablespoon of weighs 12.5 grams, the new weight W of the ceramic sugar bowl is;

=> W = 350 + 12.5 T

2b.

When the sugar bowl is full, it weighs 740 grams.

Meaning if W = 740,

=> 740 = 350 + 12.5 T

=> 740 - 350 = 12.5 T

=> 390 = 12.5 T

=> T = 390/12.5 = 31.2

The number of tablespoons of sugar that the bowl can hold is about 31

SInce number of spoons must be a whole number.
