A group of mountain climbers begin a expedition with 250 pounds of food. They plan to eat a total of 12 pounds of food per day . Write and solve a linear equation to find the number of days their food will last

Answer :

Answer:

The equation representing total food consumption in [tex]x[/tex] days can be given as:

[tex]y=12x[/tex]

where [tex]y[/tex] represents total food taken which is =250 pounds and [tex]x[/tex] represnts the number of days the food will last.

The food will last for [tex]20\frac{5}{6}[/tex] days.

Step-by-step explanation:

Total pounds of food taken at the beginning =  250 pounds

Food consumed per day = 12 pounds

Let the total food at the beginning be = [tex]y[/tex] pounds

Let number of days the food will last be = [tex]x[/tex] days

Using unitary method to find the food consumed in [tex]x[/tex] days.

If in 1 day food consumed = 12 pounds

Then, in [tex]x[/tex] days food consumption = [tex]12\times x = 12x[/tex] pounds

So,the equation representing total food consumption in [tex]x[/tex] days can be given as:

[tex]y=12x[/tex]

Total food taken =250 pounds

Plugging in [tex]y=250[/tex] in the equation:

[tex]250=12x[/tex]

Solving for  [tex]x[/tex]

Dividing both sides by 12.

[tex]\frac{250}{12}=\frac{12x}{12}[/tex]

[tex]\frac{250}{12}=x[/tex]

Simplifying fractions.

[tex]\frac{125}{6}=x[/tex]

Converting fraction to mixed number by writing quotient as whole number, remainder as numerator and divisor as denominator.

∴ [tex]x=20\frac{5}{6}[/tex] days.

Thus, the food will last for [tex]20\frac{5}{6}[/tex] days.
