Denise has taken four math tests this semester and

Viefleur [7K]

Answer:

Step-by-step explanation:

Setup an equation. Add the 5 tests together, the unknown test will be represented by x, Since there are 5 tests total, you will divide by 5. to find the average.

$\frac{89 + 85+96+87+x}{5} = 90$

To solve first multiply both side by 5.

$(5) \frac{89 + 85+96+87+x}{5} = 90 (5)$

$89 + 85+96+87+x = 450$

Add the left side and then solve for x

$357 + x = 450$

Subtract 357 from both sides

357 - 357 + x = 450 - 357

x = 93

The last test has to be a score of 93 to get an average of 90.
