Expand\;-2\left(1.5c+4.1\right)
\mathrm{Distribute\:parentheses\:using}: \:a\left(b+c\right)=ab+ac
\;a=-2,\:b=1.5c,\:c=4.1

Simplify\;-2\cdot \:1.5c-2\cdot \:4.1 \ \textgreater \  \mathrm{Multiply\:the\:numbers:}\:2\cdot \:1.5=3
-3c-2\cdot \:4.1

\mathrm{Multiply\:the\:numbers:}\:2\cdot \:4.1=8.2 \ \textgreater \  -3c-8.2 \ \textgreater \  6.3-3c-8.2

\mathrm{Subtract\:the\:numbers:}\:6.3-8.2=-1.9 \ \textgreater \  -3c-1.9

Hope this helps!

Answer:

$128.40

Step-by-step explanation:

Find the total cost of the pizza before tax.

15 × 8 = 120

Set up a proportion to find the tax.
7/100 = x/120

Cross multiply

840 = 100x

Divide both sides by 100

Tax = $8.40

$120 + $8.40 = $128.40
