I managed to do most of them. But these two problems I've been stuck on for hours. I don't know what to multiply and divide by to get the answer.
(P.s. dont give me the answers , just tell me what i need to do to find them)
7. Gary has used an average of 5 gallons of gas per week during the first three weeks of February. What is the greatest number of gallons he can use during the last week of February if he wants to decrease his average gas usage for the month by half a gallon per week?
4. Gerard is trying to get more exercise by walking an average of two miles a day. If he walks 1.8 miles on Sunday, 3 miles on Monday, 2.4 miles on Tuesday, 1.5 miles on Wednesday, 2.2 miles on Thursday, and 1.2 miles on Friday, how many miles must he walk on Saturday to meet his average goal for the week?
Thanks!
