Answer:
Step-by-step explanation:
a) Let the cost of a Pizza = $ x
Cost of three pizza's = 3 *x = 3x
cost of 3 pizza + cost of a salad = $ 20.7
3x + 3 = 20.7
b) 3x + 3 = 20. 7 {Subtract 3 from both sides}
3x = 20.7 - 3
3x = 17.7 {Divide both sides by 3}
x = 17.7/3
x = 5.9
Cost of one pizza = $ 5.9
Ok so we know he used over 700 because he was charged more than 40. Then we take the $8.10 and divide 0.45 into it. This then gives you 18 more minutes. Then add 18 to 700 and you get 718 min.
