20. At a local candy store, Malcolm purchased some 25-cent candies and some 30-cent candies. He spent a total of $4.75. Which equation below describes the number of each type of candy he bought?
A25x + 30y = 4.75
Bx + y = (4.75)/(0.25 + 0.30)
C25 + x + 30 + y = 475
D0.25/x + 0.30/y = 4.75
E x + y = 4.75 - 0.25 - 0.30
F 0.25x + 0.30y = 4.75
is it "a"
No. 25 cent = 0.25
To solve this problem, we can set up a system of equations.
Let's assume Malcolm bought x 25-cent candies and y 30-cent candies.
The cost of x 25-cent candies would be 25x cents.
The cost of y 30-cent candies would be 30y cents.
According to the problem, Malcolm spent a total of $4.75, which is equivalent to 475 cents.
Therefore, the first equation is:
25x + 30y = 475 (equation A)
Looking at the given options, we see that the correct equation is A25x + 30y = 4.75.
