Kathy earns $445 a week for 40 hours of work and $25 an hour for each hour over 40. How many hours did Kathy work if she earned $570 in one week?​

45 hours

Step-by-step explanation:

you subtract the standard price from the increased price which is 570.

you get 125 and divide by the amount of money added per hour then you get five

add that 5 to the standard hours per week

40 + 5=45

10000000000000000000000000000000

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
