Answer 1

$187

10b + 13c

Explanation:

Payment for babysitting = $10 per hour

Payment for clearing tables = $13 per hour

How much money would Stella earn in a week in which she worked 7 hours babysitting and 9 hours clearing tables?

Total weekly payments = Payment for babysitting × number of hours + Payment for clearing tables × number of hours

= 10 × 7 + 13× 9

= 70 + 117

= $187

How much money would Stella

week in which she worked b hours babysitting and c hours clearing tables?

Total weekly payments = Payment for babysitting × number of hours + Payment for clearing tables × number of hours

= 10 × b + 13 × c

= 10b + 13c
