Rhonda bought five shirts from a

densk [106]

Answer:

Option C $10+5x=24+3x$

Step-by-step explanation:

Let

x ------> the cost of each shirt

we know that

The cost of 5 shirts plus $10 (amount of money that would remain) must be equal to the cost of 3 shirts plus $24 (amount of money that would remain). Considering that the cost of the shirts is the same

The linear equation that represent this scenario is

$10+5x=24+3x$

Solve for x

$5x-3x=24-10$

$2x=14$

$x=\$7$

Determine whether y varies directly with x. If so, find the constant of variation k and write the equation

nydimaria [60]

y/x = k

6.4/4 = 1.6

11.2 / 7 =1.6

16/10 = 1.6

20.8 /13 =1.6

This is a direct variation and the constant is 1.6

y=1.6x
