Answer:
5 + (.75 * x ) + y = z
Explanation:
X = number of added ounces
Y = toppings added
Z = cost of smoothie bowl
$5 the cost of minimum bowl.
Then add that to the .75 cents multiplied by the number added ounces.
Then add that to the .50 if you get toppings.
The .50 equals the y but it could be 0 to so that's why I added Y.
