Given
Elysse paid for her sandwich and drink with a $10 bill and received $0.63 in change.
The sandwich cost $7.75 and sales tax was $0.47.
Find out the cost of her drink
To proof
Let the cost of her drink be x.
As given in the question
Elysse paid for her sandwich and drink with a $10 bill and received $0.63 in change.
Elysse paid for her sandwich and drink = 10 - 0.63
= $ 9.37
sandwich cost $7.75 and sales tax was $0.47
Than the equation becomes
x = 9.37 - (7.75 + 0.47)
x = 9.37 - 8.22
x = $ 1.15
The cost of the drink is $ 1.15.
Hence proved
Answer:
<h2>x =3.6</h2>
Step-by-step explanation:

W=15 no
W= 21 no
W= 1 Yes
If im right the question is just asking which variable is less than 15.
so the only variable that is less than 15 is 1.
Answer:
4.4%
Step-by-step explanation:
solution:
principal (p) = $300
time(t) = 3 years
interest (I ) =$40
rate (r) = ?
we know that,
I = (PTR)/100*
OR, 40 = (300 *3 * R)/100
or, 40 = (900R)/100
or, 40 = 9R
or, 40/9 = R
or, R = 4.4%
Rate(r) =4.4%
