equation for the amount of change the cashier should give her?

Answer 1

Answer: See explanation

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
