answer for A:
$160.50
Step-by-step 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 :)
