A farmer picks 242 apples on Monday and 118 apples on Tuesday. On Wednesday, she sells 109 of the apples at the market. Which equation can be used to find a, the number of apples the farmer has left?
The equation that can be used to find a, the number of apples the farmer has left, is:
242 + 118 - 109 = a
To find the number of apples the farmer has left, we need to subtract the number of apples sold from the total number of apples picked.
Let's represent the number of apples the farmer has left as 'a'.
The number of apples picked on Monday = 242
The number of apples picked on Tuesday = 118
The number of apples sold on Wednesday = 109
So, the equation to find 'a' would be:
a = (Number of apples picked on Monday + Number of apples picked on Tuesday) - Number of apples sold on Wednesday
Or, mathematically:
a = (242 + 118) - 109
