Question

Four families went out for lunch. The total food

bill came to $167. The families also left a $30 tip for the
waitress. If each family spent the same amount, about how
much did each family spend on dinner? Explain how you
found your answer.

Answer 1

If the total doesn't include the tip, and the tip isn't included in how much the families each spent, they spent $41.75 each on their food bill.

If the total includes the tip, each family spent $34.25 on their food bill and $7.50 on the tip for the waitress.

If the total doesn't include the tip, but you want to include the tip, each family spent $49.25 on the food bill AND tip.

167/4 = 41.25
(167-30)/4 = 34.25
30/4 = 7.50
(167+30)/4 = 49.25

Answer 2

Each family spent about 34.25 on dinner

Explanation:

$167 - $30 (tip) = 137

137 ÷ 4 (for each family) = 34.25

BUT

if each family is seperate than they each spent about 11.75 on dinner

167 - (30 x 4) = 47

47 ÷ 4 = 11.75

I'm pretty sure the first one is the answer though
