Step-by-step explanation:
The amount of money Savannah will have after 10 days is $0.35
<h3>Convert penny to dollar</h3>
Amount Savannah started with = 5 pennies
= $0.01 × 5
= $0.05
Additional amount per day = 3 pennies
= $0.01 × 3
= $0.03
Total savings in 10 days = 0.05 + 0.03(10)
= 0.05 + 0.3
= $0.35
Number of days it will take for her to have at least $1.50 = 0.05 + 0.03d
1.50 - 0.05 = 0.03d
1.45 = 0.03d
d = 1.45 / 0.03
d = 48.33333333333333
Approximately,
d = 48.33 days
Therefore, the number of days it will take for her to have at least $1.50 us 48.33 days
