Erik's aunt gave him $115 to spend on clothes at the mall. He bought 5 shirts that cost $11 each and a pair of pants that cost $21. How much money does Erik have left to buy more clothes?

$39

Step-by-step explanation:

He has $115 total, and he spent it on shirts and pants

First, find how much money he spent

Shirts:

5 shirts at $11 each

5*11=55

$55

Pants:

$21

To find how much he has left, subtract what he spent from the total amount of money he had to begin with

total-shirts-pants

115-55-21=39

He has $39 left to buy more clothes

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
