Rhonda bakes p pies. Mary bakes 3p pies. If together they bake 20 pies, how many pies does Mary bake?Rhonda bakes p pies. Mary bakes 3p pies. If together they bake 20 pies, how many pies does Mary bake?
I would've thought p+3=20 so 20-3=17 making it p=17 but not sure that makes sense.
p + 3p = 20
4p = 20
p = 5
23
To determine how many pies Mary bakes, we need to set up an equation using the information given in the problem. Let's assign a variable to represent the number of pies Rhonda bakes, so we'll say Rhonda bakes p pies.
Now, according to the problem, Mary bakes 3p pies. So both Rhonda and Mary together bake p + 3p = 4p pies.
We are also given that together, they bake 20 pies. This allows us to create the equation:
4p = 20
To solve for p, we can divide both sides of the equation by 4:
p = 20 / 4
Simplifying the equation, we find that p = 5.
Therefore, Rhonda bakes 5 pies, and Mary bakes 3 times that amount, or 3 * 5 = 15 pies.
So Mary bakes a total of 15 pies.
