Answer:
a. $19817.10
b. $21998.87
Step-by-step explanation:
The formula for the future value of an annuity with payments "A" and interest at rate r compounded quarterly for t years is ...
FV = A((1 +r/4)^(4t) -1)/(r/4)
The attachment shows this evaluated for ...
a. A = 900, r = 0.04, t = 5. FV = $19817.10
b. A = 450, r - 0.04, t = 10. FV = 21,998.87
Perimeter of circle = 2 pie r
Radius of circle = d/2 = 7/2
Perimeter of circle = 2 × 22/7 × 7/2 = 2×11 = 22cm
Answer:
A.1 type A pencil costs $1.40. 1 type B pencil costs $3.00.
B. Type A pencils are a better buy.

y=3x+6
Use
y=mx+b
to calculate the equation of the line, where
m
represents the slope and
b
represents the y-intercept.
Slope is equal to the change in
y
over the change in
x
, or rise over run.
