Matthew has $45 in savings and plans to save an additional $30 each month. How long will it take him to save enough for a $250 bike? What is the equation in this situation? O 250 = 450 + 30
O 250 = 30.2 + 45
O 30 30 = 2502 + 45
O 30-45x+250

Part A. It will take him 7 months

Part B. The equation is 30 - 45x + 250

Step-by-step explanation:

Part A. the answer is 7 because in 6 months Matthew will have $225 and if you add 30 you get $255.

Part B. It's the answer because its the only one that makes sense. 250 = 450 + 30. Its 45 not 450. 250 = 30.2 + 45. It's 30 not 30.2 and 30 30 well 30 30 doesn't make sense either.

P.S Can I have brainliest?

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
