Algebra one, semester one, unit two, assignment: shopping list using multi-step equationsScenario one (r+y+p)-200+=30.10÷11.50Xg=cStep one: the first thing I did was add up the cost of the red, yellow, and purple shirts and subtracted that number from 200.006X10.90=65.404X10.50=42.005X12.50=62.5065.40+42.00+62.50=169.90169.90-200=30.10Step two: after finding what is left over I divided that number by 11.50 and to check my work multiplied it back. Then I subtracted that number from 30.10 to get the answer.11.50÷30.10=22X11.50=23.00g=230.10-23.00=7.10(65.40+42.00+62.50)-200=30.10-11.50X2=7.10
Scenario two(w+c)-150.00=r÷0.50=gStep one: the first thing I did was add up the cost of the water and chips and subtract that number from the budget74X0.75=55.50150X0.40=60.0055.50+60.00=115.50115.50-150.00=34.50Step two: after finding out how much was left over I divided that by 0.50to get my answer and checked my work by multiplying34.50÷0.50=6969X0.50=34.50(55.50+60.00)-150.00=34.50÷0.50=69
