Annie and Estella were talking about how heavy their backpacks were as they prepared for a hike. They decided to weigh them to see which was heavier. Annie’s backpack weighed 18.2 lb. and Estella’s weighed 16.75 lb. How much heavier was Annie’s backpack?

Answer 1

To find out how much heavier Annie's backpack was compared to Estella's, we can subtract the weight of Estella's backpack from the weight of Annie's backpack.

Annie's backpack: 18.2 lb
Estella's backpack: 16.75 lb

Now, we perform the subtraction:

18.2 lb - 16.75 lb = 1.45 lb

Therefore, Annie’s backpack was 1.45 lb heavier than Estella’s.

Answer 2

Jolie started to workout at the gym. Over the last three days they walked on the treadmill 2.32 miles, 1.86 miles, and 1.59 miles. Jolie’s weekly goal is 12 miles. How many more miles do they need to walk this week to meet their goal?(1 point) miles

Answer 3

To find out how many more miles Jolie needs to walk to meet her weekly goal of 12 miles, we first need to calculate the total distance she has already walked over the last three days.

Jolie’s distances:

• Day 1: 2.32 miles
• Day 2: 1.86 miles
• Day 3: 1.59 miles

Now, let's add these distances together:

\[ 2.32 + 1.86 + 1.59 = 5.77 \text{ miles} \]

Next, we subtract the total distance walked from her weekly goal:

\[ 12 \text{ miles} - 5.77 \text{ miles} = 6.23 \text{ miles} \]

Therefore, Jolie needs to walk 6.23 miles more this week to meet her goal.

Answer 4

Armando went grocery shopping. He needed to buy everything on his list for a dinner at his church. This required him to go to three different stores, where he spent $32.89, $55.69, and $49.52. He was given $175 to spend on groceries. How much did he have left after all three stores?(1 point) $

Answer 5

To find out how much Armando has left after grocery shopping, we first need to calculate the total amount he spent at the three stores.

Here are his expenses:

1. Store 1: $32.89
2. Store 2: $55.69
3. Store 3: $49.52

Now, we add these amounts together:

\[ 32.89 + 55.69 + 49.52 \]

Calculating step by step:

1. \( 32.89 + 55.69 = 88.58 \)
2. \( 88.58 + 49.52 = 138.10 \)

So, the total amount spent is $138.10.

Now, we subtract this total from the amount he was given to spend:

\[ 175.00 - 138.10 = 36.90 \]

Therefore, Armando has $36.90 left after shopping.
