Aparty planner is reserving rooms for a corporate event and has the most $2000 to spend on renting the space. the sunrise room cost $170 per hour and the twilight room costs $240 per hour. select the inequality in standard from that describe this situation. use the given numbers and the following variables x=the number of hours the sunrise room is reserved. y=the number of hours the twilight room is reserved.

170x + 240y ≤ 2000.

Step-by-step explanation:

Let, the number of hours the sunrise room is reserved = x and the number of hours the twilight room is reserved = y.

It is given that, the sunrise room costs $170 per hour and twilight room costs $240 per hour.

So, the cost of sunrise room per x hours is dollars and the cost of twilight room per y hours is dollars.

Since, the maximum cost for reserving the rooms is $2000.

We get the inequality,

170x + 240y ≤ 2000.

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
