The total spent during your trip was $32 Write an equation to describe the situation.

Answer 1

The required equation is
`32=6p+3q+7r+3s`.

Explanation:

Given : Jack buys 2 bags of chips and a soda Susan buys a fruit, a bag of chips, a soda, and 2 granola bars Daniel buys 4 fruits, 2 bags of chips, and a soda Lastly, you also buy yourself 2 fruits, a bag of chips and a granola bar. The total spent during your trip was $32.

To write : An equation to describe the situation.

Solution :

Let the cost of bags of chips = p

Let the cost of soda = q

Let the cost of fruits = r

Let the cost of granola bars = s

Jack buys 2 bags of chips and a soda :

`J=2p+q`

Susan buys a fruit, a bag of chips, a soda, and 2 granola bars :

`S=r+p+q+2s`

Daniel buys 4 fruits, 2 bags of chips, and a soda :

`D=4r+2p+q`

Lastly, you also buy yourself 2 fruits, a bag of chips and a granola bar :

`M=2r+p+s`

Total spent in the trip A= $32

So, The equation form is

`A=J+S+D+M`

`32=2p+q+r+p+q+2s+4r+2p+q+2r+p+s`

`32=6p+3q+7r+3s`

The required equation is
`32=6p+3q+7r+3s`.
