ans = $ 9.18
Step-by-step explanation:
At a food restaurant, it costs $ 9.18 to get 4 orders of fries and 5 drinks.
It is obtained by adding the individual costs for a given number of orders of fries and drinks. It costs [tex]1.17f + 0.90d[/tex] for f orders of fries and d order of drinks.
Cost for an order of fries = $ 1.17
Then, the cost for 4 orders = 4 × $ 1.17 = $ 4.68
Cost for an order of drink = $ 0.90
Then, the cost for 5 drinks = 5 × $ 0.90 = $ 4.50
Then the total cost = Cost for 4 fries + Cost for 5 drinks
= $ 4.68 + $ 4.50
= $ 9.18
Similarly,
The cost for f fries = f × $ 1.17 = 1.17f
The cost for d drinks = d × $ 0.90 = 0.90d
Therefore, the total cost for f fries and d drinks = 1.17f + 0.90d
Thus, it costs $ 9.18 to get 4 orders of fries and 5 drinks and it costs 1.17f + 0.90d to get f orders of fries and d drinks.
