Jane bought some slices of cheesecakes and mango cakes for a party. She spent $60 and $40 on the cheesecakes and mango cakes respectively. Each slice of mango cake cost $2 more than each slice of cheesecake and she bought twice as many as cheesecakes as mango cakes. Find the cost of each slice of cheesecake?
Thx.

Hi

Hope this helps.

Number of pears ----- 10 units + 20

Number of plums ----- 10 units

Number of pears sold ----- 2 units + 4

Number of plums sold ----- 3 units

Number of pears left ----- 8 units + 16

Number of plums left ----- 7 units

15 units + 16 ------ 46

15 units ------ 30

1 unit ------ 2

Number of plums left ----- 7 units ------ 14

During a fund raising project, class5A raised 2/3 as much money as the total amount raised by classes 5B and 5C. Class 5B raised 1/5 as much money as the total amount raised by class 5A and 5C.

a) what fraction of the funds was raised by class5A?
b) Class 5B raised $104 less than class 5C. How much money did class 5C raise?
Pl help using model or units…Thanks.

Hi

You may present the solution in various forms, MD, using units in tabulated form or commonly using ratios.

At this juncture, maybe, the topic on ratios has not been covered in P5.

Due to time constraints, I’ll just give you some pointers for you to present it in MD or units.

A : (B+C) ------ 2 : 3 (5) -------12:18 (30)

B : (A+C) ------- 1:5 (6) -------5:25 (30)

Make the total number of units the same.

A ------ 12 units

B ------- 5 units

C ------- 13 units

a)Fraction of the funds was raised by class5A -------- 12/30 ------ 2/5

b)8 units ------ 104
1 unit ------13
Amount of money raised by Classs C ------ 13*13 ------- 169
