Question

UpStudy AI · Accepted Answer

Let the miles biked on the fourth day be $$ x $$. The average mileage is given by:

$$
\frac{44 + 47 + 56 + x}{4} = 50
$$

Calculate the sum of the first three days:

$$
44 + 47 + 56 = 147
$$

Then the equation becomes:

$$
\frac{147 + x}{4} = 50
$$

Multiply both sides by 4 to eliminate the fraction:

$$
147 + x = 200
$$

Subtract $$ 147 $$ from both sides:

$$
x = 200 - 147 = 53
$$

Thus, Jina needs to bike $$\boxed{53}$$ miles on the last day.
Jina needs to bike 53 miles on the last day to have an average of 50 miles per day.
