Front

What is the equation to calculate the total cost, c, of a phone call that lasts m minutes, given a base charge of $3.00 and $0.15 per minute?

Back

c = 3.00 + 0.15m

Front

If a printer can print 10 pages per minute and there are already 35 pages in the tray, how can we express the total pages printed after m minutes?

Back

10m + 35 = total pages printed

Front

Samuel bought 3 tires for $79.95 each and some rims for $59 each, spending a total of $534.85. What equation can be used to find the number of rims, r, he bought?

Back

3(79.95) + 59r = 534.85

Front

Maria and her three friends bought 12 bags of Takis Fuego. How can we express the number of bags of Takis Fuego, t, each person can have?

Back

4t = 12

Front

Scott charges $35 for each car and $7 per hour. If Kylie's car bill was $63, what equation represents this scenario?

Back

7x + 35 = 63

Front

What does the variable 'm' represent in the equation c = 3.00 + 0.15m?

Back

m represents the number of minutes of the phone call.

Front

In the equation 10m + 35 = 115, what does 'm' represent?

Back

m represents the number of minutes the printer has been printing.

Front

What is the total cost if Samuel bought 3 tires at $79.95 each and 2 rims at $59 each?

Back

Total cost = 3(79.95) + 2(59) = $298.85.

Front

If 4 friends share 12 bags of Takis Fuego equally, how many bags does each friend get?

Back

Each friend gets 3 bags (12 bags / 4 friends = 3 bags each).

Front

What is the first step to solve the equation 7x + 35 = 63?

Back

Subtract 35 from both sides: 7x = 28.
