The senior class had a car wash to raise money for the senior trip. It cost them $35 for supplies. They washed 75 cars
and charged $6 for each car.
Which of the following expressions represents the money they raised for their trip?
$35 + 75 - $6
$35 - 75. $6
75 . $6 - $35
75 - $35 - $6

75 x $6 - $35

Step-by-step explanation:

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 solution is 12x-6y
