brenda took her sons to lunch. the meals were $7.89, $9.27, and $11.80. she wants to leave a 10% tip.
part a: round the meal costs to the nearest dollar.
part b: add them together.
part c: move the decimal place to the left one spot to get a 10% tip.

Explanation:

Part A:

Step1: Round $7.89

Since the decimal part $0.89 \geq 0.5$, we round up. So $7.89$ rounded to the nearest dollar is $8$.

Step2: Round $9.27

Since the decimal part $0.27 < 0.5$, we round down. So $9.27$ rounded to the nearest dollar is $9$.

Step3: Round $11.80

Since the decimal part $0.80 \geq 0.5$, we round up. So $11.80$ rounded to the nearest dollar is $12$.

Part B:

Step1: Add the rounded amounts

We add the rounded values: $8 + 9 + 12$.
First, $8 + 9 = 17$, then $17 + 12 = 29$.

Part C:

Step1: Find 10% of the total

To find 10% of a number, we move the decimal point one place to the left. For the total $29$, moving the decimal point left one place gives $2.9$.

Answer:

Part A: $8, $9, $12
Part B: $29
Part C: $2.9
