Answer:
y = -1/2x + 1
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define variables</u>
Slope <em>m</em> = -1/2
y-intercept <em>b</em> = 1
<u>Step 2: Write linear function</u>
y = -1/2x + 1
70 * 0.22 = 15.4
70 + 15.4 = $85.40
The total cost is $85.40
Step-by-step explanation:
volume = [(15×11)+(½×15×8)] x 12
= (165+60) x 12
= 225×12
= 2,700 cm³
