The first error Emi made in computing the variance is failing to find the difference of 89 - 78 correctly.
<h3>What is Mean?</h3>
This is defined as the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.
In this case , sum of given numbers = 87+46+90+78+89 = 390
Divide 390 by the number of numbers which is = 5
390/5 = 78
Therefore Emi failed to find the difference.

Answer:
$25.25-lasagna, $12.25-garlic bread
Step-by-step explanation:
5L+3G=163
- 4L+4G=150
______________
4(5L+3G=163)
-5(4L+4G=150)
_____________
20L+12G=652
-20L-20G=-750
_____________
-8G=-98
-8G/-8 = -98/-8
G=$12.25
now plug that into G in any of the 2 equations at the top and you can solve for L(price of lasagna)
