Raquel works in a pet store every day after school and sometimes on weekends. She earns $5.20 per hour. If Raquel works 21 hours
a week, use front-end estimation to find out about how much she will earn in four weeks. A. $360 B. $400 C. $480 D. $520
2 answers:
$5.20 in front-end estimation: $5.00
21 in front-end estimation: 21
Multiply $5.20×21
$5.20×21= $100 a week.
$100 a week multiplied by 4 weeks $400.
$100×4= $400
I hope this help's!
