Final answer:
To find the weekly price to commute by train 4 times at $7.25 per round-trip, multiply the number of trips by the price per trip, resulting in $29.00. For the chef's spice mixture, 2/5 of 2 3/4 tablespoons is 1 1/10 tablespoons, which is not listed among the choices provided.
Step-by-step explanation:
To use the distributive property to find the weekly price to commute by train four times a week when a round-trip ticket costs $7.25, you would multiply the cost of one round-trip ticket by the number of times you will take the train in a week. The distributive property allows you to multiply a sum by a number outside the parenthesis. For example:
4 (round-trips per week) × $7.25 (cost per round-trip ticket) = $29.00
Therefore, the weekly cost to commute by train four times a week is $29.00.
As for question 3020 regarding the chef and the spice mixture, if 2 3/4 tablespoons of spices were used and parsley makes up 2/5 of the spice mixture, you would calculate:
(2 3/4 tablespoons) × (2/5) = 11/4 × 2/5 = 11/10 = 1 1/10 tablespoons
Therefore, the correct answer is not listed among the choices. The actual amount of parsley in the soup is 1 1/10 tablespoons.
