Question

missing a third
rikus 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: Define the cost of a bun

Let \( x \) be the cost of one cinnamon bun. Each family member gets one bun (\( x \)) and $2 for a beverage, so each person's cost is \( x + 2 \).

Step2: Calculate total cost for 4 people

There are 4 family members, so the total cost is \( 4(x + 2) \). We know the total bill is $28, so the equation is \( 4(x + 2) = 28 \). We can also expand it: \( 4x + 8 = 28 \), or sum the four \( x + 2 \) terms: \( (x + 2)+(x + 2)+(x + 2)+(x + 2)=28 \).

Answer:

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