Answer:
$205
Step-by-step explanation:
The cost of bike Sarah bought = $260
Discount coupon = $55
The cost Sarah paid for the bike =$260 - $55
Use the expression 260 + (- 55) to find how much Sarah paid for her bike:
![260+(-55)\\ \\=200+60+(-55)\\ \\=200+5+55+(-55)\ [\text{Note} 55+(-55)=0]\\ \\=200+5\\ \\=205](https://tex.z-dn.net/?f=260%2B%28-55%29%5C%5C%20%5C%5C%3D200%2B60%2B%28-55%29%5C%5C%20%5C%5C%3D200%2B5%2B55%2B%28-55%29%5C%20%5B%5Ctext%7BNote%7D%2055%2B%28-55%29%3D0%5D%5C%5C%20%5C%5C%3D200%2B5%5C%5C%20%5C%5C%3D205)
