Jay walks at a speed of 3 miles per hour and runs at a speed of 5 miles per hour. He walks for w hours and runs for r hours for a combined total of 14 miles. Which equation represents this situation?

• 3w + 5r = 14

• ⅓ w + ⅕ r =14

• ⅓ w + ⅕ r = 112

• 3w + 5r =112

A line in the xy-plane has a slope of 5 and passes through the point (0,14). Which equation represents this line?

• y = 14x +5

• y = -5x + 14

• y = 5x + 14

• y = -14x + 5

A veterinarian recommends that each day a certain rabbit should eat 25 calories per pound of the rabbit's weight, plus an additional 11 calories. Which equation represents this situation, where c is the total number of calories the veterinarian recommends the rabbit should eat each day if the rabbit's weight is x pounds?

• c = 25x + 11

• c = 11x + 25

• x = 25c + 11

• x= 11c + 25

A store sells two different-sized containers of blueberries. The store's sales of these blueberries totaled 896.86 dollars last month. The equation 4.51x + 6.07y = 896.86 represents this situation, where x is the number of smaller containers sold and y is the number of larger containers sold.
