James has to buy juice for his class party. there are several brands of juice at the store, and each container is a different size and price. write a formula that will james find the price per milliliter for each brand.
x=price of juice
y=number of millileters in carton
z=price per millileter

x/y

Step-by-step explanation:

Given that james has to buy juice for his class party. there are several brands of juice at the store, and each container is a different size and price

x=price of juice

y=number of millileters in carton

z=price per millileter

Price per milllitre = ?

Given

y millilitres cost = x dollars

Hence 1 ml cost = x/y dollars

z = price per milliliter = x/y dollars

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
