Matt paid $18.64 for 4 pounds of cashews. How much would he pay if he purchased 6 pounds of cashews?
Tanya [424]

Answer:

The correct answer is $27,96.

Step-by-step explanation:

First we must analyze the information we have:

We know that Matt paid $ 18.64 for 4 pounds of cashews.

Now what we want to know is how much I would pay if he bought 6 pounds of cashews.

Having 3 of 4 incognitas the most convenient thing is to do a cross-multiplication:

If he paid 18.64 ----- for 4 pounds

          He paid x ------ for 6 pounds.

x. 4 = 18.64. 6

Now we just solve the equation:

x.4 = 111.84

x = 111.84: 4

x = 27.96

In this way we show that Matt would pay $ 27.96 for 6 pounds of cashews.
