Question

please help im unsure of how to do this question, nor do I know how to do the equation for it!

Answer 1

we know that

Let

x -----> number of sandwiches

y ----> the total cost

so

From Jimmy Jhon

y=5x+10

From Subway

y=6x

If x=3 sandwich

we have

Jimmy Jhon ------> y=5(3)+10=$25

Subway --------> y=6(3)=$18

You should buy at Subway

Part B

if x=20 sandwiches

Jimmy Jhon ------> y=5(20)+10=$110

Subway --------> y=6(20)=$120

You should buy at Jimmy Jhon
