Diego rented a bicycle for four hours. The rental charges a flat fee of $10 and an additional fee of
$1.50 per hour. How much did it cost Diego to rent a bicycle for four hours?

16

Step-by-step explanation:

the initial fee is 10

he had the bike for 4 hours

1.5 x 4 = 6

6 + 10 = 16

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
