An ice-cream shop charges $3.00 for every ice cream shop parking, and an additional ¢.75 for every 10 minutes. For the entire day, the ice-cream shop made $32 dollars. What equation corresponds to the word problem above?

• .75m + 3.00= 32

• 3.00m +.75= 32

• 3.00 + 7.5p= 32

• .75p + 3.00= 32

Combine these like terms and solve it. 2a+5p+5a

• 7p + 5a

• -7a + 5p

• 7a + 5p

• 10a+5p

A baby dolphin weighed 140 pounds at birth. She gained weight at a steady rate for the first 8 months until her weight reached 620 pounds. Write and solve an equation to figure out how much weight the dolphin gained each month?

• Equation 8x+140= 620 (Solution: x= 50)

• Equation: 8+140x= 620 (Solution: x= 50)

• Equation 8x+140= 620 (Solution: x= 60)

• Equation 8+140= 620x (Solution: x= 60)
