For me, I know that this answer would be greater than 10 because for a fact, 621 and 59 aren't just perfect multiples of 10. But I don't know, because all humans don't really think alike. So, your teacher might say this doesn't work. Then in that case, I am very sorry. :0
But in any case, I hope this helps and have a good night! :D
        
             
        
        
        
Answer:
She's paid 7.50 pounds an hour
Step-by-step explanation:
7.50 x 8 = 60
 
        
             
        
        
        
For this case, the first thing we must do is define a variable.
 We have then:
 n: number of days.
 We now write the explicit formula that represents the problem.
 We have then:
 an = 4n + 15
 Where,
 15: crunches the first day
 4: increase the number 4 each day
 Answer:
 An explicit formula for the number of crunches Abbie will do on day n is:
 an = 4n + 15
