Question

missing a third
riku’s mom buys 4
cinnamon buns, one per
family member. each
person also gets $2 to
spend on a beverage. the
bill is $28 total.

one group from the card sort did not have a
matching equation.
write an equation that matches.

Explanation:

Step1: Identify the number of terms

There are 4 family members, so we have 4 terms of \(x + 2\).

Step2: Set up the equation

The sum of these 4 terms equals 28. So we write \(4(x + 2)=28\) or expanding, \( (x + 2)+(x + 2)+(x + 2)+(x + 2)=28\) which simplifies to \(4x + 8 = 28\) (but the first form with the 4 multiplied by \(x + 2\) is more direct from the diagram).

Answer:

\(4(x + 2)=28\) (or equivalent like \(4x + 8 = 28\))
