Question
A banana has 105 calories. Kalman eats 2 bananas for breakfast, after having already consumed a yogurt, which is 100 calories. Write an expression for the number of calories Kalman has eaten today.(1 point)
Let x be the expression for the number of calories Kalman has eaten today.
Kalman has already consumed a yogurt, which is 100 calories.
Kalman eats 2 bananas for breakfast, each banana has 105 calories.
So, the expression for the number of calories Kalman has eaten today is:
x = 100 + 2 * 105
Simplifying it, we get:
x = 100 + 210
Therefore, the expression for the number of calories Kalman has eaten today is:
x = 310. Answer: \boxed{310}.
