Answer:
10 hours
Step-by-step explanation:
If I have $50 in my bank account, and I want to have a total of $130 in my account. It means that I need to work enough hours to make $130 - $50 = $80.
If I make $8 per hour, and I need to make $80, then I just have to work 10 hours. ($80/8 = 10)

Answer:
<em>0.78</em>
Step-by-step explanation:
From the question, we are to represent 78% as a decimal
78% = 78/100
78/100 = 78 * 1/100
78/100 = 78 * 0.01
78/100 = 0.78
<em>hence the percent written as a decimal is 0.78</em>
