Answer:

Coupon B

Step-by-step explanation:

Given

[tex]Price = \$450[/tex]

[tex]Coupon\ A = \$80[/tex]

[tex]Coupon\ B = 20.5\%[/tex]

Required

Which coupon is better

From the question, we have:

[tex]Coupon\ A = \$80[/tex]

[tex]Coupon\ B = 20.5\%[/tex]

Coupon B means that:

[tex]Coupon\ B = 20.5\% * \$450[/tex]

[tex]Coupon\ B = 0.205 * \$450[/tex]

[tex]Coupon\ B = \$92.25[/tex]

By comparison:

Coupon B gives him a better buy because: [tex]\$92.25 > \$80[/tex]
