If a medium pizza costs $5 and a large pizza is $8, write an equation in standard form that models the possible combinations if you have $40.
Let m = medium and l = large. If you brought only medium pizzas how many could you buy? If you bought 4 medium pizzas how many large pizzas could you purchase
A medium size pizza costs $5 and a large size pizza costs $8. If a person has $40 to buy pizzas with and m medium and l large pizzas are bought, the equation obtained is:
5*m + 8*l = 40
If only medium pizzas are bought substitute l = 0 in the equation which gives m = 8
If 4 medium pizzas are bought substitute m = 4 in the equation, solving for l gives l = 5/2
Cost of medium pizza = $5
Cost of large pizza = $8
let m and l be the number of medium and large pizzas purchased respectively then
The total cost = 5m+8l
If only medium pizzas are to be purchased then l=0 and to find how much could be purchased in $40 we equate it to 40 and get
5*m+8*0 = 40 or m = 8
So we can buy 8 medium pizza for $40
However if we want 4 medium and the rest large pizzas in $40 then
5*4+8*l = 40
8*l = 40-20 = 2.5
So we can buy only 2 large pizza with 4 medium pizza
Their total cost will be 5*4+8*2 = $36 and we will be left with a balance of $4.
