Someone me if i solved these questions right

Let's look over the work! The first one is done correctly, you would add 62, 41, and 29 together to get  132.

However, for #3 it also ask you to describe and show your work, you showed your work but didn't describe what you did! You can describe it by saying you added how many pennies, nickels, and dimes he had together!

Now for #4, Alberto collected 343 more, you did your work right again, you added the 132 he had previously to the 343 he gained to get an answer of 474. Now it says 'describe two strategies you can use' Then choose one to solve.

The strategy you used was to add how many Alberto had before (132) to how much he gained (343)

(Now as for the second strategy I'm not sure of but if I do figure it out I will comment)

For the last problem, #5 you did the math correctly again! Using the strategy of subtracting the quarters from the total number of coins, (Again I don't know a second strategy)
