Bill says he can add 23 and 40 without regrouping. is bill correct? how do you know?

Step-by-step explanation:

Yes bill is correct because both numbers are easy to add without regrouping, since when each of the digit are added there won't be carried over. Also, I believe Bill should be able to do simple mathematics like 2+3, 3+5 and so on.

Then, he should be able to add 3 plus 0 in his head and keep the result as 3. And then add the other 2+4 and he will put the two result together as 63

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
