Acredit union pays 5% annual interest, compounded daily, on savings deposits. find the value after one year of $500 deposited in this account. $525.64 $25.64 $20.40 $520.40

Step-by-step

Given:

5% annual interest (APR)

compounded daily

Principal = 500

Solution:

Since it is compounded daily, we first calculate the

daily rate =  5% / 365 = 0.05/365

After one year,

future value

= 500 ( 1 + 0.05/365)^365

= 525.634 (to the tenth of a cent)

note: sometimes a year is considered to be rounded to 360 days, or 366 days for a leap year, but there is practically no difference in the results for this problem.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

ask the math teacher she or he would know lol.
