You are planning a trip of 900 miles. Your car gets about 21 mpg. Gasoline costs $1.59 per gallon. How much should you budget for gas on this trip? Round answer to the nearest ten (10)

$64.3

Step-by-step explanation:

Given the following

Total distance = 900miles

Rate per gallon = 21miles per gallon

rate = distance/time

Get the number of gallons used;

Number of gallons used = 900/21

Number of gallons = 42.857gallons

If coost of 1 gallon is $1.50

42.857gallons will cost 42.857 * 1.50

42.857gallons will cost $64.3

Hence he should budget $64.3 for the trip

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

constants mean the stopped points or the points on a graph that nothing is changing, hope this
