HELPPPPPPPPPPPP!

Penny needs 12 ounces of a snack mix that is made up of chocolate and almonds. The chocolate costs $3.50 per ounce and almonds cost $4.50 per ounce. Penny has $50 to spend and plans to spend it all.

Let x = the amount of chocolate

Let y = the amount of almonds



Determine which equations you would use to form a system of equations for this scenario.

Question 18 options:

x + y = 50


x + y = 12


3.5x + 4.5y = 50


3.5y + 4.5x = 50


3.5x + 4.5y = 12


3.5y + 4.5x = 12

Answer 1

Total ounces should be 12

and hence

x + y = 12

and total money to spend is 50, hence

3.5x + 4.5y = 50

Therefore, these are the two ✌️ equations you should use

x + y = 12

3.5x + 4.5y = 50
