Marlon saves Php 4.50 on Monday, Php 7.25 on Tuesday, Php 5.55 on Wednesday, Php 3.95 on Thursday, and Php 8.15 on Friday from his daily transportation allowance for 3 weeks. From these savings, he wants to buy a 3-layered lunch box which costs Php 195.75. How much more must he save? A) Php 107.55
B) Php 8.20
C) Php 29.40
D) Php 170.55

Php 107.55

Step-by-step explanation:

From the question, Marlon saves Php 4.50 on Monday, Php 7.25 on Tuesday, Php 5.55 on Wednesday, Php 3.95 on Thursday, and Php 8.15 on Friday . The Total amount saved will be:

= 4.50 + 7.25 + 5.55 + 3.95 + 8.15

= 29.40

Amount saved for 3 weeks will be:

= 29.40 × 3

= 88.20

Since the lunch box he wants to buy costs Php 195.75 and he has saved Php 88.20. The remaining amount will be:

= 195.75 - 88.20

= 107.55

answer: f = 32.2m

step-by-step explanation: that is the answer

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
