if matt buy's a cola at $1.69,gets a refill 3 time, for cost of $.45 each: which answer best fit the problem!
a.d=3-1.69+.45
b.1.69+3.45
c.d=1.60+0.45+3
d.3=3-1.69+0.45
none the way you typed them
it should be ...
cost = 1.69 + 3(.45)
To find the total cost of Matt buying a cola and getting three refills, you need to add up the cost of the initial cola and the cost of the three refills.
The initial cola costs $1.69. Each refill costs $0.45.
To add up the costs, you can use any given equation that correctly represents this addition. Let's evaluate each option:
a. d = 3 - 1.69 + 0.45
This equation seems incorrect because it subtracts the initial cost instead of adding it.
b. 1.69 + 3.45
This equation adds the cost of the initial cola to three times the cost of a refill. It doesn't take into account that there were three refills, so this answer is not correct either.
c. d = 1.60 + 0.45 + 3
This equation adds the cost of the initial cola at $1.60, the cost of one refill at $0.45, and the number 3. This answer incorrectly uses $1.60 for the initial cola cost instead of $1.69.
d. 3 = 3 - 1.69 + 0.45
This equation seems incorrect because it tries to equate the number 3 with the cost. It also subtracts the initial cost instead of adding it.
Based on the analysis, none of the given options correctly represent the total cost of Matt buying a cola and getting three refills.
