Greg and Alana went out to dinner

Question

Greg and Alana went out to dinner. Their dinner bill came to $68.89. If they had a $10 coupon and left a 15% tip, how much did they pay in total?

Answer 1

Hi Sophia,

Turn this into a math sentence to solve....

Price of dinner PLUS Price of dinner x .15 (tip) = cost of meal OR P + .15P is 1.15 P

BUT they had a $10 coupon, so 1.15 P - $10.00 = $68.89

You can now solve for P. To check your answer, substitute it for P and see if your calculation works:)
