Answer:
Step-by-step explanation:
<u>Given:</u>
<u>Comparing the total cost, work out the value of x:</u>
- 2x + x + 0.2 = 3.80
- 3x = 3.60
- x = 1.20
Use the FOIL method.
F = First
O = Outer
I = Inner
L = Last
Step 1: Multiply the First terms of each binomial
2x * 2 = 2x^2
Step 2: Multiply the Outer terms
2x * 1 = 2x
Step 3: Multiply the Inner terms
9 * x = 9x
Step 4: Multiply the Last terms of each expression
9 * 1 = 9
Step 5: List the results of FOIL in order
2x^2 + 2x + 9x + 9
Step 6: Combine like terms to get your final answer
2x^2 + 11x + 9
Answer:
<em><u>$250.8</u></em>
Step-by-step explanation:
13.4 = $2.85
13.4 x 15 = 111.0
111.0 = $42.75
111.0 x 6 = 666.0
666.0 - 26.0 = 640.0
$42.75 x 6 = $256.5
$2.85 x 2 = $5.07
$256.5 - $5.07 = <em><u>$250.8</u></em>
