Answer (2)
x=\frac{10*36}{9} \\ \\ \boxed{x=40 \$}"> x − t h e p r i ce o f t h e g i f t 10% o f x = 100 10 ∗ x = 10 1 ∗ x = 10 x − t h e d i sco u n t x ( 10 − 10 x = 10 10 x − x = 10 9 x − t h e n e w p r i ce 4 ∗ 9.00$ = 36$ − t h e p r i ce a f t er d i sco u n t 10 9 x = 36 => x = 9 10 ∗ 36 x = 40$
the variant A.$40.00
The original price of the gift was $40.00 before a 10% discount was applied, which means the sisters paid $36.00 after the discount. The answer choice is A. $40.00.
