Answer:
<h2>From our analysis stores B has the better buy </h2>
Step-by-step explanation:
Hey there!!!
In this problem, to know actually the store that has the better buy we need to solve for the cost of 1 foot of sandwich from individual stores.
Stores A
if 5 foot cost $42.50
1 foot will cost x
cross multiplying
x= x= $42.50/5
x= $8.5
Stores B
if 6 foot cost $49.50
1 foot will cost x
cross multiplying
x= x= $49.50/6
x= $8.24
<em>From our analysis stores B has the better buy</em>
1. m1 = -9, m2 = 9
2. x1 = -10, x2 = 10
3. n1 = -3, n2= 3
4. x1 = -2, x2 =2
