Question

A store sells 8 cans of nuts for $18. how much would it cost to buy 3 cans of nuts

Answer 1

$\bf \begin{array}{ccll}\stackrel{nuts}{cans}&\ \\\cline{1-2}8&18\\3&x\end{array}\implies \cfrac{8}{3}=\cfrac{18}{x}\implies x=\cfrac{3\cdot 18}{8}\implies x=\cfrac{27}{4}\implies x=6\frac{3}{4}$

Answer 2

Answer:

$6.75

Step-by-step explanation:

We can put the first sentence into an equation. c is equal to the cans of nuts.

8c = 18

We can solve this equation by dividing both sides by 8 to get

c = 18 ÷ 8

18 divided by 8 is 2.25

This means that each can is worth $2.25

To get the price of 3 cans, we can multiply 3 by 2.25

The answer is

$6.75
