the answer is 9

Step-by-step explanation:

You divide 72 by the interest rate to get the number of years. Examples: For an annual rate of 8%, divide 72 by 8, for a result of 9 years. So at 8% it takes about 9 years to double your money.

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

tube or goog would be a great resource to with that question
