Answer:

  • 1728 in³ in a cubic ft
  • 3.6 cubic feet (rounded to tenths)
  • 2 suitcases

Step-by-step explanation:

For part 2, you have rounded to hundredths. The question asks for the answer rounded to tenths.

__

<u>Part 3</u>

  (3.6 ft³)×(1 suitcase)/(2.9 ft³) = 3.6/2.9 suitcases ≈ 1.24 suitcases

Answer:

Cost of 1 burrito = $32

Cost of 1 taco platter = $26

Step-by-step explanation:

Let us assume the cost of 1 burrito = $ m

And the cost of 1 taco platter  = $ n

Now, according to the question:

Cost of 1 burrito + 1 taco platter = $58

⇒ m  + n  = $ 58 ..... (1)

Cost of 2 burrito + 1 taco platter = $90

⇒ 2 m  + n  = $ 90 ..... (2)

Solving both equation, we get:

(2) - (1) ⇒ 2 m  + n - m -n =  90 - 58

m = 32

⇒ n = 58 - 32  = 26  ⇒ n = 26

Hence, cost of 1 burrito = $32

and the cost of 1 taco platter = $26
