linear equation, variables

Step 1

Define the <u>variables</u>

Let

x-----> number of erasers

y-----> total cost

we know that

$y=3(0.28)+(0.38)x$

$y=0.84+(0.38)x$ ------> this is the <u>linear equation</u> that represent the situation

therefore

the answer is

Step By Step: Set this in a proportion. Since 12 out of 30 finished, it would be 12/30. Since you are dealing with percent, it would be x/100 because percent means per hundred. Set these equal to each other. 12/30 = x/100. Cross multiply. 30x = 1200. Divide. X = 40.
