math,

A jeweler is heating a gold bar. It takes 7 joules of heat
to raise the temperature of the bar 1°C. The initial
temperature of the bar is 25°C. Use this information
for Items 4–11.
4. Make a table that shows how many joules of heat
would be required to raise the temperature of the
gold bar to 26°C, 27°C, 28°C, 29°C, 30°C, and
35°C.
5. Write the equation of a function h(t) that
represents the amount of heat in joules required
to heat the bar to a temperature of t degrees
Celsius.

please explain step by step
so far i think im suppoesd to add 7 to 25 and keep going

  1. That's right. For every additional °C, it takes 7 more Joules. So, your table looks like

    °C J
    26 7
    27 14
    28 21
    ...

    h(t) = 7(t-25)
