In order to take honors-level math, Lisa must have an average of 85 on her math tests. Her scores so far are 85, 70, and 98. Wha

Mila [183]

Answer:

d) 87

Step-by-step explanation:

to solve this lets set up the equation

$\frac{85+70+98+x}{4} =85\\\frac{253+x}{4} =85$

then we multiply 4 on both sides

253+x=340

and subtract 253 on both sides

x=87

to double check take the averages

(87+85+70+98)/4=85
