The equation d=50+20w represents the relationship between dollar amount in her bank account and the number of weeks of savings.
Step-by-step explanation:
Amount in bank account = $50
Amount deposited by Priya = $20
Time period = 12
Let,
d be the dollar and w be the weeks
Therefore, we will multiply the number of week,w, with 20 to find total savings and add the amount that she has initially in her account.
Therefore,
The equation d=50+20w represents the relationship between dollar amount in her bank account and the number of weeks of savings.

<span>Quantity Equation: t + s = 20 gallons
Lemon content Eq: 20t+70s = 40*20 gallons
</span><span>Modify for elimination:
2t + 2s = 2*20
2t + 7s = 4*20
</span><span>Subtract and solve for "s":
5s = 2*20
s = 8 gallons (amt. of 70% mix needed)
t = 20-8 = 12 gallons (amt of 20% mix needed)</span>
