I NEED HELP ASAP Joe is purchasing a new cell phone plan and is trying to decide between two different options. Plan #1:
$20 per month base fee
$0.10 per minute
Plan #2:
$10 per month base fee
$0.15 per minute
a. Last month, Joe spent 160 minutes talking on the phone. If he expects to talk this much next month, which plan should he go with?

b. Joe decided to go with Plan #1. If his total bill for the next month was $25.40, how many minutes did he spend talking on the phone?

Can someone answer these problems for me

Write 17/20 as a decimal and as a percent.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
