Step-by-step explanation:
1 pizza should cost $5.65
Pizza is $5.65 then bottle of coke is $2.45
3 pizzas and coke: ($5.65*3) + $2.45 = $19.4
I solved this by setting up and solving a system of linear equations:
Variables: p = pizza, c = coke
p = c+3.2
3p+c = 19.4
Solve by substitution
3(c+3.2) + c = 19.4
4c+9.6 = 19.4
c = 2.45
Re-plug in:
p = 2.45+3.2
p = 5.65
Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>9</u></em></h2>
Step-by-step explanation:
<em><u>Let</u></em><em><u>,</u></em>
The unknown number be = x
