A moderately active 40-pound dog needs an average of 1,422 calories per day. Taryn's dog participated in a dog race this morning, so it will need more than the average calories. Taryn's dog has already eaten 711 calories, and she feeds her dog 237 calories per meal.

237x + 711 1,422

How many more meals does Taryn need to feed her dog today?
x 3
x 711
x 4
x 237

kamibug · Answer

Solve the inequality for x. :)
$$237x+711>1,422$$
Subtract 711 from both sides. 
$$237x>711$$
Divide both sides by 237.
$$x > 3$$
