Jonah and Becky went for lunch the total cost was $22.75 the restaurant added 5% tax Jonahs meal cost 1/5 more than Beckys they wanted to pay for their own after adding a 20% tip to the cost alone how much do they each have to pay

Answer 1

Answer:

Becky paid = $13.03

Jonah paid $15.64

Step-by-step explanation:

given data

total meals cost = $22.75

tax = 5%

meal cost =  1/5 more

tip = 20%

to find out

how much do they each have to pay

solution

after tax we get here total cost that is

total cost = $22.75 × ( 1 + 5%)

total cost = $23.89

and with 20% tip cost will be

total cost = $23.89 × ( 1 + 20%)

total cost = $28.67

now we consider here Becky's cost thatsi = x

so that Jonah's cost will be = $\frac{6}{5} x$

now we add both these cost that is $28.67

$28.67  = x +  $\frac{6}{5} x$

solve it we get

x = 13.03  

so Jonah' = 13.03 ×   $\frac{6}{5}$  = 15.64

Becky paid = $13.03

Jonah paid $15.64
