Miles Morals and Sharpie are shopping for bananas and penut butter. they bought their bananas from the same banana and peanut butter market. Miles spent $13.55 on 5 bunches of bananas and 4 jars of peanut and Sharpie spent $12.45 on 3 bunches of bananas and 6 jars of peanut butter. Find the price of 1 bunch of bananas and 1 jar of peanut butter using the substitution method.

Banans = 1.75

Peanut Butter = 1.20

A school principal ordered 100 pizzas for a total of $1255. Cheese pizzas cost $11.50 each, and pepperoni pizzas cost $13.00 each. Which of the following systems of linear equations can be used to determine c, the number of cheese pizzas the principal ordered, and p, the number of pepperoni pizzas the principal ordered? A) c+p100 13c + 11.50p = 1255 В) ср 100 13c +11.50p = 1255 C) c+p=100 11.50c + 13p = 1255 D) c-p=100 11.50c 13p = 1255
