Answer:
a) One kid eat tubs of yogurt = 1.3 tub of yogurt
b) One kid eat granola = 3.33 ounces
c) cost to feed one kid each morning is $1.12
Explanation:
Three kids eat tubs of yogurt = 4
Three kids eat granola = 10 ounces
Cost of one tub of yogurt = 54 cents
Cost of 10 ounces of cereal = $1.26
a) One kid eats how many tubs of yogurt in a morning?
Three kids eat tubs of yogurt = 4
One kid eat tubs of yogurt = 4/3
= 1.3 tub of yogurt
b) How many ounces of granola does a kid eat each morning?
Three kids eat granola = 10 ounces
One kid eat granola = 10/3
= 3.33 ounces
c) How much does it cost to feed one kid each morning?
Cost of 1 tub of yogurt = 54 cents
Cost of 1.3 tub of yogurt = 54*1.3 = 70.2 cents
Converting cents to dollar:
100 cents = 1 dollar
70.2 cents = $0.7
So, Cost of 1.3 tub of yogurt (for one kid)= $0.7
Cost of 10 ounces of cereal = 1.26
Cost of 1 ounce of cereal = 1.26/10
Cost of 3.33 ounces of cereal = (1.26/10)*3.33
= $0.42
Cost of 3.33 ounces of cereal (for one kid) = $0.42
Total cost for each kid = $0.42+$0.7 = $1.12
So, cost to feed one kid each morning is $1.12
