Charlotte invested $100 per year into a business for 3 years. The total value of her investment after 3 years is represented by the algebraic expression below, where x is the growth in value
each year.
100 (x3 + x2 + x)
What is the total value of her investment when x = 2?
$1200
$1400
$600
$6400

The value of her investment is $1200

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
