Step-by-step explanation:

Amaya's test scores in algebra 1 are 78 and 91.

Let she got x marks in third test

The average all the three test must be 80-89

i.e.

Multiplying all sides by 3, we get

240≤ 78+91+x≤ 267

240≤ 169+x≤ 267

Subtracting all sides by 169, we get

71≤ x≤ 98

Hence, Amaya must get marks between 71 and 98 in order to get B grade
