Final answer:
To find the student's total earnings for the week and the weekend, set up an equation and solve for x. The student's total earnings for the week and the weekend is $1550.
Step-by-step explanation:
If a student earned $620 on the weekend, which represents (2/5) of his total earnings, we are looking to find his earnings for both the week and weekend combined. To calculate his total earnings, we divide $620 by 2/5 to determine his full earnings.
To find the student's total earnings for the week and the weekend, we can set up an equation. Let's say the student's total earnings for the week is x dollars.
On the weekend, the student earned 2/5 of his total pay, which is 2/5 * x dollars. We are given that he earned $620. So we can set up the equation 2/5 * x = $620 to find x.
To solve for x, we can multiply both sides of the equation by 5/2. This gives us x = $1550. Therefore, the student's total earnings for the week and the weekend is $1550.
