Every few years, Erik's entire family gets together for a family reunion. This year, Erik's parents are hosting, and they have to cook a lot of food to feed the crowd. Erik has volunteered to do the most tedious job: shelling peas. There is a proportional relationship between the amount of time (in minutes) Erik spends shelling peas, [tex] x [/tex], and the weight (in pounds) of the peas he has shelled, [tex] y [/tex].

The equation that models this relationship is [tex] y = 0.2x [/tex].

How long does it take Erik to shell 2 pounds of peas? Write your answer as a whole number or decimal.

[tex]\square[/tex] minutes

Answer :

To solve the problem of how long it takes Erik to shell 2 pounds of peas, we can use the given relationship between the time spent shelling peas, [tex]\(x\)[/tex] (in minutes), and the weight of the peas shelled, [tex]\(y\)[/tex] (in pounds). The relationship is described by the equation:

[tex]\[ y = 0.2x \][/tex]

Here, [tex]\(0.2\)[/tex] is the proportionality constant, which tells us how many pounds of peas Erik shells per minute.

We are given that the weight of the peas Erik shells, [tex]\(y\)[/tex], is 2 pounds, and we need to find the time, [tex]\(x\)[/tex], it takes for him to shell these peas. We can substitute [tex]\(y\)[/tex] with 2 in the equation and solve for [tex]\(x\)[/tex]:

[tex]\[ 2 = 0.2x \][/tex]

To find [tex]\(x\)[/tex], we divide both sides of the equation by 0.2:

[tex]\[ x = \frac{2}{0.2} \][/tex]

By calculating the division, we find:

[tex]\[ x = 10 \][/tex]

Therefore, it takes Erik 10 minutes to shell 2 pounds of peas.
