Answer:
$18.99
Step-by-step explanation:
<u>Step 1:</u> Take the per topping amount (<em>$1.25</em>) and multiply it by the amount of toppings (<em>4</em>). $1.25x4=$5
<u>Step 2:</u> Add your toppings total (<em>$5</em>) to the base pizza cost <em>($13.99</em>). $13.99+$5=$18.99
A) w + 7 = L
B) w * L = 120
A) w = L -7 then substituting this into B)
(L-7) * L = 120
L² -7L = 120
L² -7L -120 = 0
Solving by quadratic Formula:
L1 = 15
L2 = -8
If length = 15, then width = 8
