The Miller family is taking a road trip to visit some relatives. With a full gas tank, the car has a range of 456 miles. Mr. Miller wants to stop to fill up when the range reaches 57 miles remaining. If the car averages 28.5 miles per gallon, then
the equation 456 - 28.5g = 57 represents how many gallons of gas they will use before they need to fill up. How
many gallons of gas will they use before they need to fill up?

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
