Final answer:
To determine which coupon to use, calculate the value of each coupon and compare them.
Step-by-step explanation:
To determine which coupon to use, you need to calculate the value of each coupon and compare them.
Coupon 1 offers $5 off, so the final price would be $30 - $5 = $25.
Coupon 2 offers 1/5 off, which is equivalent to a 20% discount. So, $30 - 20% = $30 - ($30 * 0.20) = $30 - $6 = $24.
Therefore, you should use Coupon 2 to get a larger discount.
