A used-car salesperson purchased a car for $4000 and sold it for 40%
more. What was the selling price of
the car?

$5600

Step-by-step explanation:

40 percent equals to 0.4

4000 times 0.4 = 1600

4000 plus 1600 equals to $5600

Answer : $5600 is selling price of car

5,600 dollars he sold it for

Step-by-step explanation:

Basically if you cross multiply, you'll do 4,000 times 40. Then divide what you get from multiplying by 100, so do 160,000 divided by 100 in this case. Then when you get that 1,600, it isn't the final step. Lastly, you'll have to add 1,600 on to 4,000 to get the markup selling price. :)

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

the answer is a beach is the best place to be
