Answer:
Option D. 3:1, $120
Step-by-step explanation:
The complete question in the attached figure
Part 1) What is the ratio between the amount of money contributed by Anna and the amount contributed by her mother?
Let
x -----> the amount of money contributed by Anna
y ----> the amount of money contributed by her mother
we know that
Looking at the table
The value of x is equal to [tex]x=\$30+\$60+\$90+\$120=\$300[/tex]
The value of y is equal to [tex]y=\$10+\$20+\$30+\$40=\$100[/tex]
Find the ratio x/y
substitute the values
[tex]\frac{x}{y}=\frac{300}{100}=\frac{3}{1}[/tex]
Part 2) What was the total amount saved in April?
we know that
To find out the total amount saved in April, adds Mon's contribution in April plus Anna's contribution in April
so
[tex](\$30+\$90)=\$120[/tex]
