Answer:
<u>A. When Rita started, she had 7 packages of saplings.</u>
<u>B. If we represent x (number of packages of saplings) on a number line graph, it will start on number 4 (number of packages Rita still has) then moves to the right to number 7, that is the number of packages when Rita started to plant.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Number of packages Rita started = x
Number of saplings per package = 5
Number of saplings planted by Rita = 15
Number of saplings left = 20
2. How many packages of saplings did she start with?
Number of packages Rita started = (Number of saplings planted by Rita + Number of saplings left)/Number of saplings per package
Replacing with the real values:
x = (15 + 20)/5
x = 35/5 = 7
<u>When Rita started, she had 7 packages of saplings.</u>
3. What would the solution look like on a number line graph?
If we represent x (number of packages of saplings) on a number line graph, it will start on number 4 (number of packages Rita still has) then moves to the right to number 7, that is the number of packages when Rita started to plant.
