Yoko earns 53 dollars each week working part time at a bookstore. She earns one additional dollar for each book she sells. Let A be the amount (in dollars) that Yoko earns each week if she sells b books. Write an equation relating A to B. Then use this equation to find the amount of money Yoko earns if she sells 36 books.

220. 4 persons approximately

Step-by-step explanation:

first consider,

1 Ton = 35274 ounce

Weight of food for one person (Breakfast+lunch+dinner) for one day = 12+18+18 = 48 ounce

Weight of food for one person (Breakfast+lunch+dinner) for ten day

= (12+18+18)*10 = 480 ounce

Maximum food the truck can carry = 3 tons = 105822 ounce

Maximum persons who could be fed = 105822/480 = 220.4

Since, one person is consuming 480 ounce of food in the duration of ten days, so you can easily obtain the number of maximum people allowed by dividing total capacity of truck in ounce which is 105822 ounce to the ounces of food consumed by one person in ten days which is 480 ounces.
