Plz help me with this question if you can also explain that would be great but you don’t have to

I'm pretty sure it's D: y= 23x

Step-by-step explanation:

D. y=23x

Step-by-step explanation:

1. The problem is telling us that he spent $115 in total in 5 weeks, in order to find out what he spends in a week lets divide 115/5

2. When you divide $ 115/5 you get a total of $23

3. Now you know that the student spends $23 each week

4. Which you have the equation now of y=23x

remider:

x is the number of weeks

y is the total amount he spent in 5 weeks

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
