Nancy works at Yogurty's for $5.35 an hour. Last week, she worked 30 hours. a) How much did she earn?
b) Nancy received a 25¢/hour raise this week. She worked 25 hours. How much did she earn?

Answer a) $160.5
Answer b) $140

Answer for A:

$160.50

explanation:

she worked for 30 hours so that means she earned $5.35 per hour. so all you have to do here is $5.35 x 30 which gives you $160.50.

Answer for B:

$140

explanation:

25¢ is the same as $0.25 so first of all, add 0.25 onto $5.35 which gives you $5.60.

Now, (this is just the same equation as part A but with different numbers), since she earns $5.60 per hour and worked 25 hours, all you have to do it $5.60 x 25 which gives you $140.

Hope this helps :)
