Jack bought 3 slices of cheese pizza and 6 slices of mushroom pizza for a total of $22.50. Grace bought 1 slices of cheese pizza and 4 slices of mushroom pizza for a total cost of $11.80. What is the cost of one slice of each type of pizza

Equations:

3c + 4m = 12.50

3c + 2m = 8.50

Subtract and solve for "m"::

2m = $4

---

Ans: m = $2.00

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
