Answer: See explanation
Step-by-step explanation:
Let the price of apples be represented by a
Let the price of guyabanos be represented by g.
Since Marcel buys 5-star apples for PhP5.00 each and 3 guyabanos for PhP32.50 each. This will be:
C = 5a + 3g
where
a = PhP5.00
g = PhP32.50
c = Total cost
Therefore, an expression for the total cost of the fruits she buys will be:
C = 5a + 3g
C = 5(5.00) + 3(32.50)
The equation for the amount of change the cashier should give her if she gives the cashier PhP200.00 will be:
= 200.00 - 5(5.00) + 3(32.50)
= 200.00 - (25.00 + 97.50)
= 200.00 - 122.50
= Php77.50
