Studdy Solution

STEP 1

What is this asking? How much does it cost to plant a bunch of trees on two separate days? Watch out! Don't forget to calculate the cost for *each* day separately before adding them together!

STEP 2

1. Calculate Tuesday's cost
2. Calculate Wednesday's cost
3. Calculate total cost

STEP 3

Alright, so on Tuesday, we planted **18** trees.
Each tree costs $78\$78 to plant.
To find the total cost for Tuesday, we **multiply** the number of trees by the cost per tree.
This makes sense, right?
Because each tree adds $78\$78 to our total bill!

STEP 4

So, Tuesday's cost is 18$7818 \cdot \$78.
Let's break down the multiplication: 10$78=$78010 \cdot \$78 = \$780 and 8$78=$6248 \cdot \$78 = \$624.
Adding those together, we get $780+$624=$1404\$780 + \$624 = \$1404.
So, planting **18** trees on Tuesday cost us $1404\$1404!

STEP 5

Now, let's move on to Wednesday.
We planted **23** trees on Wednesday, and each tree *still* costs $78\$78 to plant.
We'll use the same logic as before: **multiply** the number of trees by the cost per tree!

STEP 6

Wednesday's cost is 23$7823 \cdot \$78.
Let's break it down: 20$78=$156020 \cdot \$78 = \$1560 and 3$78=$2343 \cdot \$78 = \$234.
Adding those together gives us $1560+$234=$1794\$1560 + \$234 = \$1794.
Wow, Wednesday was a busy day!
Planting **23** trees cost us $1794\$1794!

STEP 7

Now, for the grand finale!
We want to find the *total* cost for *both* days.
We know Tuesday cost us $1404\$1404 and Wednesday cost us $1794\$1794.
To find the total cost, we simply **add** these two amounts together.

STEP 8

So, the total cost is $1404+$1794=$3198\$1404 + \$1794 = \$3198.
That's it!

STEP 9

The total cost to plant the trees on Tuesday and Wednesday is $3198\$3198.
