An investor divides $10,000 of his savings into two accounts that will earn him interest. One account is a high-risk high yield account that ends up giving him an average of 12.1% interest per annum that year. The other is a safer savings account that gives him 3.1% interest per annum. If at the end of one year he has a total of $10,805 in the two accounts combined, how much did he invest at each rate?

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
