Answer: C) $1.05
Step-by-step explanation:
Given : All batteries were listed on sale for 15% off the regular price.
Discount price = 15%=0.15
Keith usually pays $6.99 for a battery for his watch.
Discount amount = [tex]\text{Price of a battery }\times\text{Discount percent}[/tex]
[tex]=\$6.99\times0.15\\\\=\$1.0485\approx\$1.05\ \ \text{[ Rounded to the nearest cent.]}[/tex]
Hence, discount will Keith receive on his purchase of a new watch battery = $1.05
