Question

Travis and Paula went to lunch. Travis ordered a sandwich for $7.50, and Paula ordered a burger for $5.25. After lunch, they left 15% tip for their

waiter. How much money did they spend altogether ?

Answer 1

first you have to add $7.50 and $5.25, that will equal $12.75, with that you move the decimal point to the left, tha will make 1.275 which will round up to $1.28, tha will be 10% of $12.75, more or less, with that you divide $1.28 and get .64 (cents) which would be 5% of $12.75, add up .64 and $1.28, you get $1.92, so they gave $1.92 in tip, if you want to find the total, you add up $12.75 and $1.92, where you get your answer: $14.67

Answer 2

Answer: $14.66

Explanation:

Cost of Travis sandwich= $7.50, Cost of Paula burger= $5.25.

Total cost= $7.50 + $5.25

= $12.75

After lunch, they left 15% tip for their

waiter. We calculate 15% of $12.75

= 15/100 × 12.75

= 0.15 × 12.75

= $1.91

Amount of money spent altogether will be the addition of the cost of sandwich and burger plus the tip. This will be:

= $12.75 + $1.91

= $14.66
