Cindy says she found a shortcut for doing multiplication problems. When she multiplies 3 x 24, she says, “3 x 4 is 12 ones, or 1 ten and 2 ones. Then, there’s just 2 tens left in 24, so add it up, and you get 3 tens and 2 ones.” Do you think Cindy’s shortcut works? Explain your thinking in words, and justify your response using a model or partial product.

step-by-step explanation:

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .
