Question

At the corner store near Billy’s house, loose mixed nuts cost $1.75 per 100 g. Write an equation to represent the amount of mixed nuts, n, he can buy if he has d dollars. Then, use your equation to determine how many grams of mixed nuts Billy can buy if he has $5.

Answer 1

First you will need to convert the $1.75 per 100 g to get how much it will cost for just 1 gram.

$1.75/100=$.175

Next you want to right an equation that includes n(for amount of nuts) and d for how much money you have.

d=.175*n

the amount of money will equal .175 times the number of grams of nuts you have,

Now to find how much you can buy you will substitute in 5 for d.

5=.175n

Divide .175 from both sides.

5/.175=.175n/.175

n=28.57 grams(rounding to the hundredths place. )
