Darius filled up his gas tank with 24 gallons of gas. For each mile that he drives, he uses 0.06 gallons of gas. How may gallons of gas are left in the tank after driving 240 miles?

Step-by-step explanation:

Step one:

Given that the capacity of the gas tank is 24 gallons.

we know that 1 mile will consume 0.06 gallons

therefore x miles will consume 0.06x gallons.

the consumption for any distance is given as

0.06x gallons.

Step two:

if x=240 miles

then the gallons consume will be

0.06(240)=14.4 gallons

Step three:

the remaining gallons of gas in the tank will be

24-14.4=9.6 gallons

The reamining gallons will be 9.6 gallons

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

828. all there is to it!
