Answer:
<h2>4200 times</h2>
Step-by-step explanation:
349 698 17450+698=18148
18,148 is the answer
The answer is 1 hour 30 minutes. Think of the 50 and 20 mins as 5/6 and 2/6
M + t + w = 19
t = 2m
w = 2m - 6
now we sub
m + (2m) + (2m - 6) = 19...combine like terms
5m - 6 = 19
5m = 19 + 6
5m = 25
m = 25/5
m = 5 <== she sold 5 books on Monday
t = 2m......t = 2(5)...t = 10 <== she sold 10 books on Tuesday
w = 2m - 6....w = 2(5) - 6....w = 10 - 6...w = 4 <== she sold 4 books on Wednesday.
