Joey's Cafe sold 20% regular coffee and 80% decaffeinated coffee.

Step-by-step explanation:

We are given that the cafe served 35 coffees. We are also told that of those 35 coffees, 7 coffees were regular.

Therefore, we can divide the number of regular coffees by the total number of coffees sold to get the percentage of regular coffees.

Our ratio will be set up as 7 regular coffees : 35 total coffees. We can also represent this as a fraction.

Therefore, of the coffees sold at the cafe, 20% of those coffees were regular.

Additionally, we can subtract this percentage from 100 to find out how much of the sales were decaffeinated coffee.

Joey's Cafe sold 80% decaffeinated coffee.

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
