Your friend asked you to help him to solve a problem in Math. Write a letter back to your friend explaining how to solve the problem, step by step. Remember that your friend is struggling in Math so please include the formulas and be specific as possible. btw pls make it 9 sentences

we need the formula  but it should be 10 times 14 times 6

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
