Question

On bonfire night at sleepaway camp, Lily's counselor puts marshmallows, graham crackers, and several chocolate bars on the snack table. Lily uses

3/4
of a chocolate bar to make herself a s'more. Now 3 1/4
chocolate bars remain on the table.
Which equation can you use to find the number of chocolate bars b the counselor puts on the table?
3/4b = 3 1/4
b - 3/4 = 3 1/4
b + 3 1/4 = 3/4
b + 3/4 = 3 1/4

Answer 1

The correct equation is:

b - 3/4 = 3 1/4

Step-by-step explanation:

Lily used 3/4 of a chocolate bar, so the remaining chocolate bars can be found by subtracting 3/4 from the total number of chocolate bars b:

b - 3/4 = remaining chocolate bars

The problem tells us that there are 3 1/4 remaining chocolate bars, so we can substitute this value in the equation and solve for b:

b - 3/4 = 3 1/4

b = 3 1/4 + 3/4

b = 4

Therefore, the counselor put 4 chocolate bars on the table.
