Answer:

9 cans of soup and the 4 frozen dinners were purchased

Step-by-step explanation:

Let x represent the number of cans of soup purchased.

Let y represent the number of frozen dinners purchased.

Lincoln purchased a total of 13 cans of soup and frozen dinners. This means that

x + y = 13

Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium. The 13 cans of soup and frozen dinners which he purchased collectively contain 4450 mg of sodium. This means that

250x + 550y = 4450 - - - - - - - - -1

Substituting x = 13 - y into equation 1, it becomes

250(13 - y) + 550y = 4450

3250 - 250y + 550y = 4450

- 250y + 550y = 4450 - 3250

300y = 1200

y = 1200/300

y = 4

Substituting y = 4 into x = 13 - y, it becomes

x = 13 - 4 = 9

Alla [95]
<span>It is cheaper for Tim to return the car on time and pay the refueling costs. If the gas tank on the car is half empty and the rental agency charges $4.50 per gallon the costs to refill for him would be. $27.00 plus the $5.00 refueling fee. This would equal $32.00. If Tim returns the car late, he faces a $32.00 charge including the cost to refuel the car on his own. The cost of returning the car a day late is not the same costs as returning the car on time. Choice b is the better option and the best choice.</span>
