Hello,
x=0 ==> y=-5 ==> (0,5)
x=1 ==> y=7-5=2 ==>(1,2)
x=2 ==> y=14-5=9 ==> (2,9)
Coffee = $12
Tea = $8
Total cost = $2600
Total Case = 250
Assumed all 250 cases are Tea
250 x 8 = 2000
Difference in amount
2600 - 2000 = 600 (so $600 was from the coffee)
Difference between the price of coffee and tea
12 - 8 = $4
Number of cases of coffee
600 ÷ 4 = 150
Number of cases of tea
250 - 150 = 100
150 cases of coffee were ordered
the pattern is that you take each number and multiply it by 3
