Sarah and Bryan went shopping and spent a total of $47.50. Bryan spent $15.50 less than Sarah spent. How much did Bryan spend.

$16.00

Step-by-step explanation:

Eq1:

s

+

b

=

47.50

"Bryan spent

$

15.50

less than what Sarah spent":

Eq2:

b

=

s

−

15.50

Now we need to solve for

b

. First we'll solve Eq1 to get an expression for

s

. Then we can substitute that result into Eq2 to find

b

, which is what we are searching for!

Solving Eq1 for

s

:

Eq3:

s

=

47.50

−

b

Eq3 -> Eq2:

b

=

(

47.50

−

b

)

−

15.50

b

=

32.00

−

b

2

b

=

32.00

⇒

b

=

16.00

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
