Question

Howard needs 25 grams of trail mix that is made up of pretzels and peanuts. The pretzels cost $1 per gram, peanuts cost $3.50 per gram. Howard has $45 to spend and plans to spend it all. Let x= the amount of pretzels. Let y= amount of peanuts.

Answer choices:
X+y=45
X+y=25
X+3.5y=45
Y+3.5x=25
Y+3.5x=45
X+3.5y=25

Answer 1

B and C.

Explanation:

To solve this problem, we need to set up a system of equations based on the given information. Let x be the amount of pretzels (in grams) and y be the amount of peanuts (in grams) that Howard needs to buy.

Then we have:x + y = 25 (since Howard needs 25 grams of trail mix in total)

1x + 3.5y = 45 (since the pretzels cost $1 per gram and the peanuts cost $3.50 per gram, and Howard has $45 to spend)

Therefore, the correct answer choices are:X+y=25 and X+3.5y=45, or B and C.
