Answer:

a) $515

b) $530.45

c) The amount grew faster in the second year. Because after each year, the amount she has increase, and then the 3% will be applied over a higher amount than before, generating more profit than the previous year.

Step-by-step explanation:

a)

After one year, the amount increased is 3% of the inicial value, so it is 0.03 * 500 = $15

So Sofia has 500 + 15 = $515 at the end of the year.

b)

After the second year, the amount will increase by 3%, but now the amount is 515, so we have 0.03 * 515 = $15.45

So Sofia has 515 + 15.45 = 530.45 at the end of the second year.

c)

The amount grew faster in the second year. Because after each year, the amount she has increase, and then the 3% will be applied over a higher amount than before, generating more profit than the previous year.

Alex787 [66]

Answer:

48% were carrot sticks.

52% were apple slices.

Step-by-step explanation:

Given that:

Total number of snacks in the tray = 25

Number of carrot sticks = 12

Number of apple slices = 25 - 12 = 13

Percent of carrot sticks = \frac{Number\ of\ carrot\ sticks}{Total\ Number}*100

Percent of carrot sticks= \frac{12}{25}*100

Percent of carrot sticks = 0.48 * 100 = 48%

Percent of apple slices = \frac{13}{25}*100

Percent of apple slices = 52%

Hence,

48% were carrot sticks.

52% were apple slices.

garri49 [273]

Answer: He ate 8 grapes on Monday.

Step-by-step explanation:

Let be "x" the number of grapes Godswill ate on Monday.

You know that he ate 6 more grapes than he had on Monday. This can be expressed with:

x+6

Since each day that week, he ate 6 more grapes than the day before and he realized on Friday he had eaten a total of 100 grapes this week, you can write the following expression and solve for "x":

x+(x+6)+(x+12)+(x+18)+(x+24)=100\\\\5x+60=100\\\\x=\frac{40}{5}\\\\x=8
