Answer: Game land sells 20 crayons for 5 cents less.
Step-by-step explanation:
Hi, to answer this question we have to calculate the price per crayon in each store, by dividing the amount paid in each case by the number of crayons that each store offers.
Toy world (T): 25/4 = 6.25 cents per crayon
Game land (G): 30/5 = 6 cents per crayon
Now, we have to multiply the cost per crayon by 20.
T=6.25 x 20 = 125 cents
G=6 x 20 =120 cents
So, comparing both costs, Game land sells 20 crayons for 5 cents less.
125-120 = 5 cents
Answer:
More than 250 miles
Step-by-step explanation:
Rental cost of company A is $80 + $0.6 per mile driven and company B also has a rental cost of $30 + $0.8 per mile driven.
To find the moment when company A rental cost matches that of company B,we have to create an equation that is ideal for both parties.
80 +0.6x = 30 + 0.8x
Where x is the number of miles traveled by both trucks.
Simplifying the above equation, we have
0.2x = 50 divide both sides by 0.2
= 250 miles is when both rental cost matches .
Therefore, the number of miles needed to be driven so as the rental cost of company A to better company B should be more than 250 miles
