The value of danielle's investments is modeled by the equation V (t)=3t^2+70t+100

where t represents the number of months after she made her initial investment. jeffrey has no money invested in stocks, but he deposits the same amount every month into a savings account that he opened at the same time as danielle. his savings account balance can be modeled by the equation V (t)=50t+275

after how many months will the value of danielle's investment be equal to jeffery's savings account?

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
