Lila evaluates the expression using the following steps:(−7.13+63.97)+(−54.8−3.4)−71.1+(−58.2)−129.3Describe the error that Lila
mihalych1998 [28]

Lila's error was that she added -7.13 to 63.97 to get -71.1

Lila steps are as folows

(−7.13 + 63.97) + (−54.8 − 3.4) = −71.1 + (−58.2) = −129.3

In the first bracket, Lila was suppose to subtract 7.31 from 63.97 since there is a negative in front of 7.31.

So, the correct expression should be

(−7.13 + 63.97) + (−54.8 − 3.4) = 56.84 + (−58.2) = 56.84 - 58.2 = −1.36

So, Lila's error was that she added -7.13 to 63.97 to get -71.1

krek1111 [17]

Answer:

A = P (1 + i)^n      A is the final amount

                            i = interest / period

                            n = number of periods

A = 315 * (1 + .015)^1.5 = 322.11
