For this case what we should do is write the expression step by step.
"She believes that her total will be $ 98"
To get to this we have:
10 × $ 8 + $ 20
Rewriting:
10 × $ 8 + $ 20
$ 80 + $ 20
$ 100
Rate approximately equal to $ 98 with an extra $ 2.
Answer:
An expression that could be used to estimate the reasonableness of Simone's total is:
10 × $ 8 + $ 20
