Question

erica earns money by tutoring and babysitting. she always tutors for 5 hours each week, but the amount she babysits changes from week to week. write an expression to represent the total number of hours erica works each week. tutoring hours + babysitting hours let x be the number of hours erica babysits. write an expression to represent the total number of hours erica works each week.

Explanation:

1. First, identify the known and unknown quantities:

• The number of hours Erica tutors each week is a constant, which is 5 hours.
• The number of hours Erica babysits each week is represented by the variable \( x \).

1. Then, to find the total number of hours she works each week, we need to add the number of hours she tutors and the number of hours she babysits.

• The formula for the total hours \( T \) is the sum of tutoring hours and babysitting hours.
• So, \( T = 5 + x \) (or \( T=x + 5\), since addition is commutative).

Answer:

The expression to represent the total number of hours Erica works each week is \( 5 + x \) (or \( x+5 \)).
