Emily was given a gift card for a coffee shop. Each morning, Emily uses the card to buy one cup of coffee. Each cup of coffee costs $2 and after buying 7 cups of coffee, the card had a $6 remaining balance. Write an equation for A(x),A(x), representing the amount money remaining on the card after buying xx cups of coffee.

A(x) = 2x + 6

Step-by-step explanation:

Step 1:  Make an equation

A(x) = 2x + 6

A(7) = 2(7) + 6

A(7) = 14 + 6

A(7) = 20

This shows that the total that Emily had on the gift card was $20

 A(x) = 2x + 6

A(x) = 20 - 2x

Step-by-step explanation:

Initial anoiunt:

6 + 7(2) = 20

A(x) = 20 - 2x

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

d no solution
