Question

To decorate her bedroom, Lisa spent $62.89 on new bedding, $48.26 on paint, and $81.99 on accessories. About how much did she spend to decorate her bedroom?

Answer 1

the problem says "about how much" which indicates they are most likely looking for an approximation

perhaps, try rounding to the nearest dollar

for example: $62.89. look at the ones digit (2), then moving to the next digit over ---> it's an 8, which is at least 5, so we round up to $63. repeat this logic with the rest of the numbers and add up the approximations
